Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Correct Solution:
```
def main():
alpha = "QWERTYUIOPLKJHGFDSAZXCVBNM"
s = input()
n = len(s)
i = 0
st = []
ans = 0
while i < n:
j = i
if s[i] in alpha:
while j+1 < n and s[j+1] in alpha:
j += 1
name = s[i:j+1]
i = j
ans += st.count(name)
st.append(name)
elif s[i] == '.':
st.pop(-1)
i += 1
print(ans)
if __name__ == '__main__':
main()

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Correct Solution:
```
s = input()
a = []
cnt = 0
s = ':' + s
s1 = ''
flag = False
for i in range(len(s)):
if flag:
if s[i] != '.' and s[i] != ':' and s[i] != ',':
s1 += s[i]
continue
else:
a.append(s1)
flag = False
for j in range(len(a) - 1):
if a[j] == a[-1]:
cnt += 1
if s[i] != '.' and s[i] != ':' and s[i] != ',':
flag = True
s1 = s[i]
elif s[i] == '.':
a.pop()
print(cnt)

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Correct Solution:
```
#!/usr/bin/env python3
tree = input().strip()
def get_answer(tree, start_index = 0, prev = []):
colon_index = tree.find(':', start_index)
period_index = tree.find('.', start_index)
name_end_index = colon_index if ((colon_index != -1) and (colon_index < period_index)) else period_index
name = tree[start_index:name_end_index]
answer = prev.count(name)
if ((colon_index == -1) or (period_index < colon_index)):
return (answer, period_index+1)
else:
# Recurse
prev_names = prev + [name]
next_start = colon_index
while tree[next_start] != '.':
(sub_answer, next_start) = get_answer(tree, next_start+1, prev_names)
answer += sub_answer
return (answer, next_start+1)
print(get_answer(tree)[0])

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

name = s[i:j+1]
first = True
i = j
ans += st.count(name)
elif s[i] == ":":
first = True
st.append(name)
elif s[i] == ',':
first = True
elif s[i] == '.' and first:
first = False
else:
st.pop(-1)
i += 1
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Correct Solution:
```
import sys
from array import array # noqa: F401
from collections import Counter
def input():
return sys.stdin.buffer.readline().decode('utf-8')
class Employee(object):
def __init__(self, name: str):
self.name = name
self.sub = []
def add_sub(self, sub: 'Employee'):
self.sub.append(sub)
def __repr__(self):
return self.name
stack = [Employee('*** God ***')] # type: list[Employee]
s = input().rstrip()
n, l = len(s), 0
while l < n:
if s[l] == '.':
stack.pop()
l += 1
continue
if s[l] == ',':
l += 1
continue
r = l
while 65 <= ord(s[r]) <= 90:
r += 1
e = Employee(s[l:r])
if stack:
stack[-1].add_sub(e)
if s[r] == ':':
stack.append(e)
l = r + 1
def rec(e: Employee):
count = 0
name_dict = Counter()
for sub in e.sub:
cnt, d = rec(sub)
count += cnt
for k, v in d.items():
name_dict[k] += v
count += name_dict[e.name]
name_dict[e.name] += 1
return count, name_dict
print(rec(stack[0])[0])

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Correct Solution:
```
s = input()
a = []
cnt = 0
s = ':' + s
s1 = ''
flag = False
for i in range(len(s)):
if flag:
if s[i] != '.' and s[i] != ':' and s[i] != ',':
s1 += s[i]
continue
else:
a.append(s1)
flag = False
for j in range(len(a) - 1):
if a[j] == a[-1]:
cnt += 1
if s[i] != '.' and s[i] != ':' and s[i] != ',':
flag = True
s1 = s[i]
elif s[i] == '.':
a.pop()
print(cnt)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The Beroil corporation structure is hierarchical, that is it can be represented as a tree. Let's examine the presentation of this structure as follows:
* employee ::= name. | name:employee1,employee2, ... ,employeek.
* name ::= name of an employee
That is, the description of each employee consists of his name, a colon (:), the descriptions of all his subordinates separated by commas, and, finally, a dot. If an employee has no subordinates, then the colon is not present in his description.
For example, line MIKE:MAX.,ARTEM:MIKE..,DMITRY:DMITRY.,DMITRY... is the correct way of recording the structure of a corporation where the director MIKE has subordinates MAX, ARTEM and DMITRY. ARTEM has a subordinate whose name is MIKE, just as the name of his boss and two subordinates of DMITRY are called DMITRY, just like himself.
In the Beroil corporation every employee can only correspond with his subordinates, at that the subordinates are not necessarily direct. Let's call an uncomfortable situation the situation when a person whose name is s writes a letter to another person whose name is also s. In the example given above are two such pairs: a pair involving MIKE, and two pairs for DMITRY (a pair for each of his subordinates).
Your task is by the given structure of the corporation to find the number of uncomfortable pairs in it.
<image>
Input
The first and single line contains the corporation structure which is a string of length from 1 to 1000 characters. It is guaranteed that the description is correct. Every name is a string consisting of capital Latin letters from 1 to 10 symbols in length.
Output
Print a single number — the number of uncomfortable situations in the company.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
You are given a boolean function of three variables which is defined by its truth table. You need to find an expression of minimum length that equals to this function. The expression may consist of:
* Operation AND ('&', ASCII code 38)
* Operation OR ('|', ASCII code 124)
* Operation NOT ('!', ASCII code 33)
* Variables x, y and z (ASCII codes 120-122)
* Parentheses ('(', ASCII code 40, and ')', ASCII code 41)
If more than one expression of minimum length exists, you should find the lexicographically smallest one.
Operations have standard priority. NOT has the highest priority, then AND goes, and OR has the lowest priority. The expression should satisfy the following grammar:
E ::= E '|' T | T
T ::= T '&' F | F
F ::= '!' F | '(' E ')' | 'x' | 'y' | 'z'
Input
The first line contains one integer n — the number of functions in the input (1 ≤ n ≤ 10 000).
The following n lines contain descriptions of functions, the i-th of them contains a string of length 8 that consists of digits 0 and 1 — the truth table of the i-th function. The digit on position j (0 ≤ j < 8) equals to the value of the function in case of <image>, <image> and <image>.
Output
You should output n lines, the i-th line should contain the expression of minimum length which equals to the i-th function. If there is more than one such expression, output the lexicographically smallest of them. Expressions should satisfy the given grammar and shouldn't contain white spaces.

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
from collections import Counter
def contains(a, b):
for k in a.keys():
if a[k] > b[k]:
return False
return True
_ = int(input())
letters = input()
T = int(input())
memo = {}
for t in range(T):
name = input()
ctr = Counter(name)
ctr_encoded = tuple(sorted(ctr.items()))
if ctr_encoded in memo:
print(memo[ctr_encoded])
continue
letters_ctr = Counter()
for i in range(len(letters)):
letters_ctr[letters[i]] += 1
# ctr[k] <= letters_ctr[k] for all k in ctr
if contains(ctr, letters_ctr):
print(i + 1)
memo[ctr_encoded] = i + 1
break

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
import copy
n = int(input())
s = input()
d = {}
for i in range(n):
if s[i] not in d:
d[s[i]] = [i]
else:
d[s[i]].append(i)
m = int(input())
for _ in range(m):
t = input()
dx = {i:0 for i in d}
ma = 0
for i in t:
ma = max(ma,d[i][dx[i]])
dx[i]+=1
print(ma+1)

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
n =int(input())
main = input()
dic ={}
for i in range(n):
if main[i] in dic:
dic[main[i]].append(i)
else:
dic[main[i]]=[i]
num = int(input())
for i in range(num):
a = 0
name = input()
dic_name ={}
for i in range(len(name)):
if name[i] in dic_name:
dic_name[name[i]]+=1
else:
dic_name[name[i]]=0
for k in dic_name:
a=max(a,dic[k][dic_name[k]])
print(a+1)

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
n=int(input())
s=input()
d={}
for i in range(len(s)):
if(s[i] in d):
d[s[i]].append(i+1)
else:
d[s[i]]=[i+1]
for _ in range(int(input())):
res=[]
s=input()
f={}
for i in range(len(s)):
if(s[i] in f):
f[s[i]]+=1
else:
f[s[i]]=1
for key,value in f.items():
res.append(d[key][value-1])
print(max(res))

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
from collections import Counter,defaultdict
n=int(input())
s=str(input())
a=defaultdict(list)
for i in range(len(s)):
a[s[i]].append(i)
for j in range(int(input())):
t=Counter(input())
#print(t)
p=max([a[o][t[o]-1]for o in t])
print(p+1)

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Provide tags and a correct Python 3 solution for this coding contest problem.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Correct Solution:
```
n = int(input())
l = list(input())
d = dict()
for i in set(l):
d[i] = ([k for k, n in enumerate(l) if n == i])
for i in range(int(input())):
s = input()
mx = 0
dc = dict()
for i in s:
j = dc.get(i, 0)
mx = max(mx, d[i][j])
dc[i] = j +1
print(mx+1)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
The letters shop showcase is a string s, consisting of n lowercase Latin letters. As the name tells, letters are sold in the shop.
Letters are sold one by one from the leftmost to the rightmost. Any customer can only buy some prefix of letters from the string s.
There are m friends, the i-th of them is named t_i. Each of them is planning to estimate the following value: how many letters (the length of the shortest prefix) would s/he need to buy if s/he wanted to construct her/his name of bought letters. The name can be constructed if each letter is presented in the equal or greater amount.
* For example, for s="arrayhead" and t_i="arya" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="harry" 6 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="ray" 5 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="r" 2 letters have to be bought ("arrayhead").
* For example, for s="arrayhead" and t_i="areahydra" all 9 letters have to be bought ("arrayhead").
It is guaranteed that every friend can construct her/his name using the letters from the string s.
Note that the values for friends are independent, friends are only estimating them but not actually buying the letters.
Input
The first line contains one integer n (1 ≤ n ≤ 2 ⋅ 10^5) — the length of showcase string s.
The second line contains string s, consisting of exactly n lowercase Latin letters.
The third line contains one integer m (1 ≤ m ≤ 5 ⋅ 10^4) — the number of friends.
The i-th of the next m lines contains t_i (1 ≤ |t_i| ≤ 2 ⋅ 10^5) — the name of the i-th friend.
It is guaranteed that ∑ _{i=1}^m |t_i| ≤ 2 ⋅ 10^5.
Output
For each friend print the length of the shortest prefix of letters from s s/he would need to buy to be able to construct her/his name of them. The name can be constructed if each letter is presented in the equal or greater amount.
It is guaranteed that every friend can construct her/his name using the letters from the string s.

You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples

Correct Solution:
```
s1, s2 = map(str, input().split('^'))
l1, l2 = 0, 0
for i in range(len(s1)):
if s1[i].isdigit():
l1 += int(s1[i]) * (len(s1) - i)
for i in range(len(s2)):
if s2[i].isdigit():
l2 += int(s2[i]) * (i + 1)
if l1 == l2:
print('balance')
elif l1 > l2:
print('left')
else:
print('right')

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output
balance
Input
9===^==1
Output
left
Input
2==^7==
Output
right
Input
41^52==
Output
balance

Correct Solution:
```
s = input()
pivot = s.find('^')
value = 0
for i in range(len(s)):
if s[i].isdigit():
value += int(s[i]) * (i - pivot)
if value < 0:
print('left')
elif value == 0:
print('balance')
else:
print('right')

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output
balance
Input
9===^==1
Output
left
Input
2==^7==
Output
right
Input
41^52==
Output
balance

Correct Solution:
```
s = input().strip()
n = len(s)
i = s.find('^')
left = 0
right = 0
l = i - 1
r = i + 1
while l >= 0 or r < n:
if l >= 0 and s[l] != '=':
left += int(s[l])*(i - l)
l -= 1
else:
l -= 1
if r < n and s[r] != '=':
right += int(s[r]) * (r - i)
r += 1
else:
r += 1
if left == right:
print("balance")
elif left > right:
print("left")
else:
print("right")

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output

Correct Solution:
```
a=input()
p=a.index('^')
c=sum((i-p)*int(y) for i,y in enumerate(a) if y.isdigit())
print([['balance','right'][c>0],'left'][c<0])

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.

The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples

Correct Solution:
```
s = input()
p = s.index('^')
f = 0
for i in range(len(s)):
if s[i]=='1':
f = f-((p-i)*1)
elif s[i]=='2':
f = f - ((p-i)*2)
elif s[i]=='3':
f = f - ((p-i)*3)
elif s[i]=='4':
f = f - ((p-i)*4)
elif s[i]=='5':
f = f - ((p-i)*5)
elif s[i]=='6':
f = f - ((p-i)*6)
elif s[i]=='7':
f = f - ((p-i)*7)
elif s[i]=='8':
f = f - ((p-i)*8)
elif s[i]=='9':
f = f - ((p-i)*9)
if f<0:
print("left")
elif f>0:
print("right")
else:
print("balance")

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output
balance
Input
9===^==1
Output
left
Input
2==^7==
Output
right
Input
41^52==
Output
balance

Correct Solution:
```
s=[n for n in input()]
k=s.index('^')
a=s[:k][::-1]
b=s[k+1:]
m=0
for n in range(len(a)):
if ord('0')<=ord(a[n])<=ord('9'):
m+=int(a[n])*(n+1)
p=0
for n in range(len(b)):
if ord('0')<=ord(b[n])<=ord('9'):
p+=int(b[n])*(n+1)
if m==p:
print('balance')
elif m>p:
print('left')
elif m<p:
print('right')

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output
balance
Input
9===^==1
Output
left
Input
2==^7==
Output
right
Input
41^52==
Output
balance

Correct Solution:
```
a = input()
i = 0
r = 0
l = 0
while(a[i] != "^"):
i = i+1
k = i
for j in range(i):
if(a[j]!= "="):
l = l +k*int(a[j])
k = k-1
k = 1
i +=1
while(i<len(a)):
if(a[i]!= "="):
r = r+k*int(a[i])
i = i+1
k = k+1
if(r==l):
print("balance")
elif(l>r):
print("left")
else:
print("right")

Provide tags and a correct Python 3 solution for this coding contest problem.
You have a description of a lever as string s. We'll represent the string length as record |s|, then the lever looks as a horizontal bar with weights of length |s| - 1 with exactly one pivot. We will assume that the bar is a segment on the Ox axis between points 0 and |s| - 1.
The decoding of the lever description is given below.
* If the i-th character of the string equals "^", that means that at coordinate i there is the pivot under the bar.
* If the i-th character of the string equals "=", that means that at coordinate i there is nothing lying on the bar.
* If the i-th character of the string equals digit c (1-9), that means that at coordinate i there is a weight of mass c on the bar.
Your task is, given the lever description, print if it will be in balance or not. Assume that the bar doesn't weight anything. Assume that the bar initially is in balance then all weights are simultaneously put on it. After that the bar either tilts to the left, or tilts to the right, or is in balance.
Input
The first line contains the lever description as a non-empty string s (3 ≤ |s| ≤ 106), consisting of digits (1-9) and characters "^" and "=". It is guaranteed that the line contains exactly one character "^". It is guaranteed that the pivot of the lever isn't located in any end of the lever bar.
To solve the problem you may need 64-bit integer numbers. Please, do not forget to use them in your programs.
Output
Print "left" if the given lever tilts to the left, "right" if it tilts to the right and "balance", if it is in balance.
Examples
Input
=^==
Output

Input
9===^==1
Output

Correct Solution:
```
# -*- coding: utf-8 -*-
s1, s2 = input().split('^')
s1 = s1[::-1]
l1 = sum([(i+1) * int(s1[i]) for i in range(len(s1)) if s1[i] != '='])
l2 = sum([(i+1) * int(s2[i]) for i in range(len(s2)) if s2[i] != '='])
print('balance' if l1==l2 else 'left' if l1>l2 else 'right')

Provide tags and a correct Python 3 solution for this coding contest problem.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Correct Solution:
```
import sys
from array import array # noqa: F401
def input():
return sys.stdin.buffer.readline().decode('utf-8')
n = int(input())
name = {'void': 'void'}
errtype = 'errtype'
def resolve(t):
nest = 0
while t[-1] == '*':
nest += 1
t = t[:-1]
while t[0] == '&':
nest -= 1
t = t[1:]
if t not in name:
return errtype
t = name[t]
while nest < 0 and t[-1] == '*':
nest += 1
t = t[:-1]
if nest < 0:
return errtype
else:
return t + '*' * nest
def f(s):
if s[:7] == errtype:
return errtype
else:
return s
ans = []
for _ in range(n):
query = input().split()
if query[0] == 'typeof':
ans.append(f(resolve(query[1])))
else:
name[query[2]] = resolve(query[1])
print(*ans, sep='\n')

Provide tags and a correct Python 3 solution for this coding contest problem.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Provide tags and a correct Python 3 solution for this coding contest problem.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Correct Solution:
```
n=int(input())
def Ref(v):
stars=0
ands=0
nam=""
for item in v:
if(item=='*'):
stars+=1
elif(item=='&'):
ands+=1
else:
nam+=item
if(nam not in T):
return "errtype"
x=T[nam]
if(x=="errtype"):
return str(x)
x+=stars
x-=ands
if(x<0):
return "errtype"
return x
T={'void':0}
for i in range(n):
s=input()
if(s[4]=='d'):
s=s[8:].split()
v=str(s[0])
name=str(s[1])
T[name]=Ref(v)
else:
s=s[7:]
x=Ref(str(s))
if(x=="errtype"):
print(x)
else:
print("void"+("*"*x))

Provide tags and a correct Python 3 solution for this coding contest problem.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Correct Solution:
```
types = {'void':'void', 'errtype':'errtype'}
def getRealType(type_expr):
expr_type = type_expr.strip('&*')
full_type_name = type_expr.replace(expr_type, types.get(expr_type, "errtype"))
base_type = full_type_name.strip('&*')
if base_type == "void":
addr_count = full_type_name.count('*')
deref_count = full_type_name.count('&')
if deref_count > addr_count:
return "errtype"
return base_type + "*" * (addr_count - deref_count)
else:
return "errtype"
def setTypeAlias(type_expr, alias_name):
types[alias_name] = getRealType(type_expr)
n = int(input())
for _ in range(n):
operator = input().split()
command = operator[0]
if command == "typedef":
setTypeAlias(operator[1], operator[2])
else:
print(getRealType(operator[1]))

Provide tags and a correct Python 3 solution for this coding contest problem.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Correct Solution:
```
types = {'void':'void', 'errtype':'errtype'}
def getRealType(type_expr):
expr_type = type_expr.strip('&*')
full_type_name = type_expr.replace(expr_type, types.get(expr_type, "errtype"))
base_type = full_type_name.strip('&*')
if base_type == "void":
addr_count = full_type_name.count('*')
deref_count = full_type_name.count('&')
if deref_count > addr_count:
return "errtype"
return base_type + "*" * (addr_count - deref_count)
else:
return "errtype"
def setTypeAlias(type_expr, alias_name):
types[alias_name] = getRealType(type_expr)
n = int(input())
for _ in range(n):
operator = input().split()
command = operator[0]
if command == "typedef":
setTypeAlias(operator[1], operator[2])
else:
print(getRealType(operator[1]))

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Programmer Vasya is studying a new programming language &K*. The &K* language resembles the languages of the C family in its syntax. However, it is more powerful, which is why the rules of the actual C-like languages are unapplicable to it. To fully understand the statement, please read the language's description below carefully and follow it and not the similar rules in real programming languages.
There is a very powerful system of pointers on &K* — you can add an asterisk to the right of the existing type X — that will result in new type X * . That is called pointer-definition operation. Also, there is the operation that does the opposite — to any type of X, which is a pointer, you can add an ampersand — that will result in a type &X, to which refers X. That is called a dereference operation.
The &K* language has only two basic data types — void and errtype. Also, the language has operators typedef and typeof.
* The operator "typedef A B" defines a new data type B, which is equivalent to A. A can have asterisks and ampersands, and B cannot have them. For example, the operator typedef void** ptptvoid will create a new type ptptvoid, that can be used as void**.
* The operator "typeof A" returns type of A, brought to void, that is, returns the type void**...*, equivalent to it with the necessary number of asterisks (the number can possibly be zero). That is, having defined the ptptvoid type, as shown above, the typeof ptptvoid operator will return void**.
An attempt of dereferencing of the void type will lead to an error: to a special data type errtype. For errtype the following equation holds true: errtype* = &errtype = errtype. An attempt to use the data type that hasn't been defined before that will also lead to the errtype.
Using typedef, we can define one type several times. Of all the definitions only the last one is valid. However, all the types that have been defined earlier using this type do not change.
Let us also note that the dereference operation has the lower priority that the pointer operation, in other words &T * is always equal to T.
Note, that the operators are executed consecutively one by one. If we have two operators "typedef &void a" and "typedef a* b", then at first a becomes errtype, and after that b becomes errtype* = errtype, but not &void* = void (see sample 2).
Vasya does not yet fully understand this powerful technology, that's why he asked you to help him. Write a program that analyzes these operators.
Input
The first line contains an integer n (1 ≤ n ≤ 100) — the number of operators. Then follow n lines with operators. Each operator is of one of two types: either "typedef A B", or "typeof A". In the first case the B type differs from void and errtype types, and besides, doesn't have any asterisks and ampersands.
All the data type names are non-empty lines of no more than 20 lowercase Latin letters. The number of asterisks and ampersands separately in one type in any operator does not exceed 10, however if we bring some types to void with several asterisks, their number may exceed 10.
Output
For every typeof operator print on the single line the answer to that operator — the type that the given operator returned.
Examples
Input
5
typedef void* ptv
typeof ptv
typedef &&ptv node
typeof node
typeof &ptv
Output
void*
errtype
void
Input
17
typedef void* b
typedef b* c
typeof b
typeof c
typedef &b b
typeof b
typeof c
typedef &&b* c
typeof c
typedef &b* c
typeof c
typedef &void b
typeof b
typedef b******* c
typeof c
typedef &&b* c
typeof c
Output
void*
void**
void
void**
errtype
void
errtype
errtype
errtype
Note
Let's look at the second sample.
After the first two queries typedef the b type is equivalent to void*, and с — to void**.
The next query typedef redefines b — it is now equal to &b = &void* = void. At that, the с type doesn't change.
After that the с type is defined as &&b* = &&void* = &void = errtype. It doesn't influence the b type, that's why the next typedef defines c as &void* = void.
Then the b type is again redefined as &void = errtype.
Please note that the c type in the next query is defined exactly as errtype******* = errtype, and not &void******* = void******. The same happens in the last typedef.

Provide tags and a correct Python 3 solution for this coding contest problem.
When Serezha was three years old, he was given a set of cards with letters for his birthday. They were arranged into words in the way which formed the boy's mother favorite number in binary notation. Serezha started playing with them immediately and shuffled them because he wasn't yet able to read. His father decided to rearrange them. Help him restore the original number, on condition that it was the maximum possible one.
Input
The first line contains a single integer n (1 ⩽ n ⩽ 10^5) — the length of the string. The second line contains a string consisting of English lowercase letters: 'z', 'e', 'r', 'o' and 'n'.
It is guaranteed that it is possible to rearrange the letters in such a way that they form a sequence of words, each being either "zero" which corresponds to the digit 0 or "one" which corresponds to the digit 1.
Output
Print the maximum possible number in binary notation. Print binary digits separated by a space. The leading zeroes are allowed.
Examples
Input
4
ezor
Output
0
Input
10
nznooeeoer
Output
1 1 0
Note
In the first example, the correct initial ordering is "zero".
In the second example, the correct initial ordering is "oneonezero".
Tags: implementation, sortings, strings
Correct Solution:
```
length = int(input())
string = input()
contador_0 = 0
contador_1 = 0
for letter in string:
if letter == 'z':
contador_0 += 1
elif letter == 'n':
contador_1 += 1
string = ''
for contador in range(contador_1):
string += '1 '
for contador in range(contador_0):
string += '0 '
string=''.join(list(string)[:-1])
print(string)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.
Tags: dp
Correct Solution:
```
m=1000000007
s=input()
if(s.count('w') or s.count('m')):
print(0)
else:
dp=[1,1]
n=len(s)
for i in range(1,n):
if(s[i]==s[i-1] and (s[i]=='u' or s[i]=='n')):
dp.append((dp[i]+dp[i-1])%m)
else:
dp.append(dp[i]%m)
#print(dp)
print(dp[-1]%m)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Correct Solution:
```
f = [1, 2]
const = 10 ** 9 + 1
s = input()
if "m" in s or "w" in s:
print(0)
else:
ans = 1
const = 10 ** 9 + 7
check = False
count = 0
if s[0] == "u" or s[0] == "n":
check = True
count = 1
for i in range(1, len(s)):
f.append((f[-1] + f[-2]) % const)
if s[i] == s[i - 1]:
count += 1
elif check:
ans = (ans * f[count - 1]) % const
count = 0
check = False
if s[i] == "u":
count = 1
check = "u"
elif s[i] == "n":
count = 1
check = "n"
else:
check = False
count = 0
elif s[i] == "u":
count = 1
check = "u"
elif s[i] == "n":
count = 1
check = "n"
else:
check = False
count = 0
if check:
ans = (ans * f[count - 1]) % const
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Correct Solution:
```
# import sys
# input = sys.stdin.readline
s = input()
n = len(s)
A = []
mod = 10**9+7
L = [0,1,2]
for i in range(10**5+3):
L.append((L[-1]+L[-2]) % mod)
nn=0
uu=0
for i in range(n):
if s[i] == "n":
if nn == 0:
nn = 1
A.append(1)
else:
A[-1] += 1
else:
nn = 0
if s[i] == "u":
if uu == 0:
uu = 1
A.append(1)
else:
A[-1] += 1
else:
uu = 0
ans = 1
for i in range(len(A)):
ans = (ans * L[A[i]]) % mod
if s.count("m") > 0 or s.count("w") > 0:
ans = 0
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Correct Solution:
```
mod = 10**9+7
def cmb(n, r, mod=mod):
if ( r<0 or r>n ):
return 0
r = min(r, n-r)
return g1[n] * g2[r] * g2[n-r] % mod
NN = 10**5 # 使うデータによって変える
g1 = [1, 1] # 元テーブル
g2 = [1, 1] #逆元テーブル
inverse = [0, 1] #逆元テーブル計算用テーブル
for i in range( 2, NN + 1 ):
g1.append( ( g1[-1] * i ) % mod )
inverse.append( ( -inverse[mod % i] * (mod//i) ) % mod )
g2.append( (g2[-1] * inverse[-1]) % mod )
import sys
input = sys.stdin.readline
S = input().rstrip()
N = len(S)
pre = '-1'
ans = 1
A = []
c = 0
for s in S:
if s == 'm' or s == 'w':
ans = 0
break
if s == 'n':
if pre == 'n':
c += 1
else:
if c > 1:
A.append(c)
c = 1
elif s == 'u':
if pre == 'u':
c += 1
else:
if c > 1:
A.append(c)
c = 1
else:
if c > 1:
A.append(c)
c = 0
pre = s
A.append(c)
if ans == 0:
print(0)
else:
for a in A:
tmp = 1
n, m = a-1, 1
while n >= m:
tmp += cmb(n, m)
tmp %= mod
n -= 1
m += 1
ans = ans * tmp % mod
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.
Tags: dp
Correct Solution:
```
s = input()
s_ct = 0
n_ct = 0
ans = []
dp = [0 for _ in range(len(s)+5)]
dp[0] = 1
dp[1] = 1
dp[2] = 2
a = 1
for i in range(3,len(dp)):
dp[i] = (dp[i-1]+dp[i-2])%(10**9+7 )
for i in range(len(s)):
if(s[i]=='m'):
a = 0
if(s[i]=='w'):
a=0
if(s[i]=='u'):
if n_ct:
ans.append(n_ct)
n_ct = 0
s_ct+=1
elif s[i] == 'n':
if s_ct:
ans.append(s_ct)
s_ct = 0
n_ct+=1
else:
if s_ct:
ans.append(s_ct)
s_ct = 0
if n_ct:
ans.append(n_ct)
n_ct = 0
if s_ct:
ans.append(s_ct)
s_ct = 0
if n_ct:
ans.append(n_ct)
n_ct = 0
for i in ans:
a = (a*dp[i])%(10**9 + 7)
print(a)

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Correct Solution:
```
s = input()
L = [0] * (len(s) + 1)
inf = 1000000007
L[0] = 1
L[1] = 1
for i in range(1, len(s)):
if s[i] == 'm' or s[i] == 'w':
break
if s[i] == 'u':
if s[i - 1] == 'u':
L[i + 1] = (L[i] + L[i - 1]) % inf
else:
L[i + 1] = L[i]
elif s[i] == 'n':
if s[i - 1] == 'n':
L[i + 1] = (L[i] + L[i - 1]) % inf
else:
L[i + 1] = L[i]
else:
L[i + 1] = L[i]
if s[0] == 'm' or s[0] == 'w':
L[len(s)] = 0
print(L[len(s)])

Provide tags and a correct Python 3 solution for this coding contest problem.
Constanze is the smartest girl in her village but she has bad eyesight.
One day, she was able to invent an incredible machine! When you pronounce letters, the machine will inscribe them onto a piece of paper. For example, if you pronounce 'c', 'o', 'd', and 'e' in that order, then the machine will inscribe "code" onto the paper. Thanks to this machine, she can finally write messages without using her glasses.
However, her dumb friend Akko decided to play a prank on her. Akko tinkered with the machine so that if you pronounce 'w', it will inscribe "uu" instead of "w", and if you pronounce 'm', it will inscribe "nn" instead of "m"! Since Constanze had bad eyesight, she was not able to realize what Akko did.
The rest of the letters behave the same as before: if you pronounce any letter besides 'w' and 'm', the machine will just inscribe it onto a piece of paper.
The next day, I received a letter in my mailbox. I can't understand it so I think it's either just some gibberish from Akko, or Constanze made it using her machine. But since I know what Akko did, I can just list down all possible strings that Constanze's machine would have turned into the message I got and see if anything makes sense.
But I need to know how much paper I will need, and that's why I'm asking you for help. Tell me the number of strings that Constanze's machine would've turned into the message I got.
But since this number can be quite large, tell me instead its remainder when divided by 10^9+7.
If there are no strings that Constanze's machine would've turned into the message I got, then print 0.
Input
Input consists of a single line containing a string s (1 ≤ |s| ≤ 10^5) — the received message. s contains only lowercase Latin letters.
Output
Print a single integer — the number of strings that Constanze's machine would've turned into the message s, modulo 10^9+7.
Examples
Input
ouuokarinn
Output
4
Input
banana
Output
1
Input
nnn
Output
3
Input
amanda
Output
0
Note
For the first example, the candidate strings are the following: "ouuokarinn", "ouuokarim", "owokarim", and "owokarinn".
For the second example, there is only one: "banana".
For the third example, the candidate strings are the following: "nm", "mn" and "nnn".
For the last example, there are no candidate strings that the machine can turn into "amanda", since the machine won't inscribe 'm'.

Correct Solution:
```
import sys
# def recur(pre,p,pos,maxx,temp):
# if pos == len(pre):
# maxx[0] = max(maxx[0],temp)
# return
# for i in range(0,p+1):
# if i < len(pre[pos]) :
# temp = temp + pre[pos][i]
# recur(pre,p-i,pos+1,maxx,temp)
# temp = temp - pre[pos][i]
RI = lambda : [int(x) for x in sys.stdin.readline().split()]
ri = lambda : sys.stdin.readline().strip()
# for _ in range(int(ri())):
mod = 10**9+7
st = ri()
dp = [0]*2
dp[1] = 1
for i in range(len(st)):
if st[i] == 'm' or st[i] == 'w':
dp[1] = 0
break
if st[i] == 'n' and st[i-1] == 'n':
temp = dp[1]
dp[1] = (dp[0]+dp[1])%mod
dp[0] = temp
elif st[i] == 'u' and st[i-1] == 'u':
temp = dp[1]
dp[1] = (dp[0]+dp[1])%mod
dp[0] = temp
else:
dp[0] = dp[1]
print(dp[1])

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Correct Solution:
```
from functools import reduce
n = int(input())
s1, s2 = str(input()), str(input())
print((10 ** sum([(s1[i] == '?') + (s2[i] == '?') for i in range(n)]) - (not reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)], False)) * reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (ord(s2[i]) - ord('0') + 1) if s1[i] == '?' else (10 - ord(s1[i]) + ord('0')) if s2[i] == '?' else 1 for i in range(n)], 1) - (not reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)], False)) * reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (10 - ord(s2[i]) + ord('0')) if s1[i] == '?' else (ord(s1[i]) - ord('0')) + 1 if s2[i] == '?' else 1 for i in range(n)], 1) + (not reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)], False) and not reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)], False)) * reduce(lambda x, y: (x * y) % 1000000007, [10 if s1[i] == '?' and s2[i] == '?' else 1 for i in range(n)], 1)) % 1000000007)

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Correct Solution:
```
n = int(input())
C = 10**9+7
a = input()
s = input()
d = [[0, 0, 0, 1]]
for q in range(n):
d.append(d[-1][::])
if a[q] != '?' and s[q] != '?':
if int(a[q]) < int(s[q]):
d[-1][1] = d[-1][3] = 0
d[-1][0] += d[-2][3]
d[-1][2] += d[-2][1]
elif int(a[q]) > int(s[q]):
d[-1][0] = d[-1][3] = 0
d[-1][1] += d[-2][3]
d[-1][2] += d[-2][0]
elif s[q] != '?':
d[-1][2] *= 10
d[-1][0] += d[-2][3]
d[-1][1] += d[-2][3]
d[-1][0] *= int(s[q])+1
d[-1][1] *= 10-int(s[q])
d[-1][0] -= d[-2][3]
d[-1][1] -= d[-2][3]
d[-1][2] += d[-2][0]*(9-int(s[q]))+d[-2][1]*int(s[q])
elif a[q] != '?':
d[-1][2] *= 10
d[-1][0] += d[-2][3]
d[-1][1] += d[-2][3]
d[-1][1] *= int(a[q]) + 1
d[-1][0] *= 10 - int(a[q])
d[-1][0] -= d[-2][3]
d[-1][1] -= d[-2][3]
d[-1][2] += d[-2][1] * (9 - int(a[q])) + d[-2][0] * int(a[q])
else:
d[-1][3] *= 10
d[-1][2] *= 100
d[-1][0] *= 55
d[-1][1] *= 55
d[-1][0] += d[-2][3]*45
d[-1][1] += d[-2][3]*45
d[-1][2] += d[-2][0]*45+d[-2][1]*45
d[-1][0] %= C
d[-1][1] %= C
d[-1][2] %= C
d[-1][3] %= C
print(d[-1][2])

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Correct Solution:
```
from functools import reduce
n = int(input())
s1, s2 = str(input()), str(input())
b1 = reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)], False)
b2 = reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)], False)
s = sum([(s1[i] == '?') + (s2[i] == '?') for i in range(n)])
ans1 = reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (ord(s2[i]) - ord('0') + 1) if s1[i] == '?' else (10 - ord(s1[i]) + ord('0')) if s2[i] == '?' else 1 for i in range(n)], 1)
ans2 = reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (10 - ord(s2[i]) + ord('0')) if s1[i] == '?' else (ord(s1[i]) - ord('0')) + 1 if s2[i] == '?' else 1 for i in range(n)], 1)
ans3 = reduce(lambda x, y: (x * y) % 1000000007, [10 if s1[i] == '?' and s2[i] == '?' else 1 for i in range(n)], 1)
print((10 ** s - (not b2) * ans1 - (not b1) * ans2 + (not b1 and not b2) * ans3) % 1000000007)

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Correct Solution:
```
from functools import reduce
n = int(input())
s1, s2 = str(input()), str(input())
b1 = reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)], False)
b2 = reduce(lambda x, y: x or y, [s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)], False)
s = sum([(s1[i] == '?') + (s2[i] == '?') for i in range(n)])
ans1 = reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (ord(s2[i]) - ord('0') + 1) if s1[i] == '?' else (10 - ord(s1[i]) + ord('0')) if s2[i] == '?' else 1 for i in range(n)], 1)
ans2 = reduce(lambda x, y: (x * y) % 1000000007, [55 if s1[i] == '?' and s2[i] == '?' else (10 - ord(s2[i]) + ord('0')) if s1[i] == '?' else (ord(s1[i]) - ord('0')) + 1 if s2[i] == '?' else 1 for i in range(n)], 1)
ans3 = reduce(lambda x, y: (x * y) % 1000000007, [10 if s1[i] == '?' and s2[i] == '?' else 1 for i in range(n)], 1)
print((10 ** s - (not b2) * ans1 - (not b1) * ans2 + (not b1 and not b2) * ans3) % 1000000007)

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Correct Solution:
```
from functools import reduce
n, s1, s2, f1, f2 = int(input()), str(input()), str(input()), lambda x: reduce((lambda a, b: (a * b) % 1000000007), x, 1), lambda x: reduce((lambda a, b: a or b), x, False)
print((10 ** sum([(s1[i] == '?') + (s2[i] == '?') for i in range(n)]) - (not f2([s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)])) * f1([55 if s1[i] == '?' and s2[i] == '?' else (ord(s2[i]) - ord('0') + 1) if s1[i] == '?' else (10 - ord(s1[i]) + ord('0')) if s2[i] == '?' else 1 for i in range(n)]) - (not f2([s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)])) * f1([55 if s1[i] == '?' and s2[i] == '?' else (10 - ord(s2[i]) + ord('0')) if s1[i] == '?' else (ord(s1[i]) - ord('0')) + 1 if s2[i] == '?' else 1 for i in range(n)]) + (not f2([s1[i] != '?' and s2[i] != '?' and ord(s1[i]) < ord(s2[i]) for i in range(n)]) and not f2([s1[i] != '?' and s2[i] != '?' and ord(s1[i]) > ord(s2[i]) for i in range(n)])) * f1([10 if s1[i] == '?' and s2[i] == '?' else 1 for i in range(n)])) % 1000000007)

Provide tags and a correct Python 3 solution for this coding contest problem.
Yaroslav thinks that two strings s and w, consisting of digits and having length n are non-comparable if there are two numbers, i and j (1 ≤ i, j ≤ n), such that si > wi and sj < wj. Here sign si represents the i-th digit of string s, similarly, wj represents the j-th digit of string w.
A string's template is a string that consists of digits and question marks ("?").
Yaroslav has two string templates, each of them has length n. Yaroslav wants to count the number of ways to replace all question marks by some integers in both templates, so as to make the resulting strings incomparable. Note that the obtained strings can contain leading zeroes and that distinct question marks can be replaced by distinct or the same integers.
Help Yaroslav, calculate the remainder after dividing the described number of ways by 1000000007 (109 + 7).
Input
The first line contains integer n (1 ≤ n ≤ 105) — the length of both templates. The second line contains the first template — a string that consists of digits and characters "?". The string's length equals n. The third line contains the second template in the same format.
Output
In a single line print the remainder after dividing the answer to the problem by number 1000000007 (109 + 7).

Note
The first test contains no question marks and both strings are incomparable, so the answer is 1.
The second test has no question marks, but the given strings are comparable, so the answer is 0.

Correct Solution:
```
n = int(input())
a = input()
b = input()
mod = int(1e9+7)
x, y, z = 1, 1, 1
for i in range(n):
if a[i] == '?' and b[i] == '?':
x = (x * 55) % mod
y = (y * 55) % mod
z = (z * 10) % mod
elif a[i] == '?':
x = (x * (10 - int(b[i]))) % mod
y = (y * (int(b[i]) + 1)) % mod
elif b[i] == '?':
x = (x * (int(a[i]) + 1)) % mod
y = (y * (10 - int(a[i]))) % mod
else:
if int(a[i]) < int(b[i]): x = 0
if int(a[i]) > int(b[i]): y = 0
if a[i] != b[i]: z = 0
res = pow(10, a.count('?') + b.count('?'), mod)
print((res - x - y + z) % mod)

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
s = str(input())
ll = sum(map(str.islower, s))
ul = sum(map(str.isupper, s))
if ul > ll:
print(s.upper())
else:
print(s.lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
a = input()
l = len(a)
count = 0
for i in a:
if i.isupper():
count += 1
if count <= int(l/2):
print(a.lower())
else:
print(a.upper())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house

matrix
Tags: implementation, strings
Correct Solution:
```
s=list(input())
p=""
l=[]
x=[]
for i in range(len(s)):
if s[i]==s[i].upper():
l.append(s[i])
elif s[i]==s[i].lower():
x.append(s[i])
if len(l)>len(x):
print(p.join(s).upper())
else:
print(p.join(s).lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
word = input()
uppercases = 0
lowercases = 0
for letter in word:
if letter.upper() == letter:
uppercases += 1
else:
lowercases += 1
if uppercases > lowercases:
print(word.upper())
else:
print(word.lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
s=input();print(s.upper() if sum(1 for c in s if c.isupper())>sum(1 for c in s if c.islower())else s.lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
w = input()
upp = 0
low = 0
for i in w:
if i.isupper() == True:
upp += 1
else:
low += 1
if upp <= low:
print(w.lower())
else:
print(w.upper())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
n=input()
l=0
u=0
for i in range(len(n)):
if n[i].islower():
l+=1
elif n[i].isupper():
u+=1
if l>u:
print(n.lower())
elif l<u:
print(n.upper())
else:
print(n.lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is very upset that many people on the Net mix uppercase and lowercase letters in one word. That's why he decided to invent an extension for his favorite browser that would change the letters' register in every word so that it either only consisted of lowercase letters or, vice versa, only of uppercase ones. At that as little as possible letters should be changed in the word. For example, the word HoUse must be replaced with house, and the word ViP — with VIP. If a word contains an equal number of uppercase and lowercase letters, you should replace all the letters with lowercase ones. For example, maTRIx should be replaced by matrix. Your task is to use the given method on one given word.
Input
The first line contains a word s — it consists of uppercase and lowercase Latin letters and possesses the length from 1 to 100.
Output
Print the corrected word s. If the given word s has strictly more uppercase letters, make the word written in the uppercase register, otherwise - in the lowercase one.
Examples
Input
HoUse
Output
house
Input
ViP
Output
VIP
Input
maTRIx
Output
matrix
Tags: implementation, strings
Correct Solution:
```
word = str(input())
sumUppercaseLetters = 0
sumLowercaseLetters = 0
for i in word:
if i.isupper():
sumUppercaseLetters += 1
elif i.islower():
sumLowercaseLetters += 1
if sumUppercaseLetters > sumLowercaseLetters:
print(word.upper())
elif sumLowercaseLetters > sumUppercaseLetters:
print(word.lower())
else:
print(word.lower())
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
s = input()
i = s[1:].find('at') + 1
s = s[:i] + '@' + s[i+2:]
while True:
i = s[1:].find('dot')
if i == -1:
break
i += 1
if i+3 == len(s):
break
s = s[:i] + '.' + s[i+3:]
print(s)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
s=input()
at=s.find('at',1)
s=s[:at]+'@'+s[at+2:]
pos=1
while 1:
ns=''
dot=s.find('dot',pos,-1)
if dot==-1:
break
ns+=s[:dot]
ns+='.'
pos=dot+1
ns+=s[dot+3:]
s=ns
print(s)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
s=input()
if s[:3]=="dot" or s[:2]=="at" or s[len(s)-2:]=="at" or s[len(s)-3:]=="dot":
if s[:3]=="dot":
t=s[3:]
a=t.split('dot')
l=".".join(a)
b=l.find("at")
o=l[:b]+"@"+l[b+2:]
q="dot"+o
if q[-1]==".":
a=q[:len(q)-1]
s=a+"dot"
elif q[-1]=="@":
a=q[:len(q)-1]
s=a+"at"
else:
s=q
if s[:2]=="at":
t=s[2:]
a=t.split('dot')
l=".".join(a)
b=l.find('at')
o=l[:b]+"@"+l[b+2:]
q="at"+o
if q[-1]==".":
a=q[:len(q)-1]
s=a+"dot"
elif q[-1]=="@":
a=q[:len(q)-1]
s=a+"at"
else:
s=q
if s[len(s)-3:]=="dot" and s[:3]!="dot" and s[:2]!="at":
t=s[:len(s)-3]
a=t.split('dot')
l=".".join(a)
b=l.find('at')
q=l[:b]+"@"+l[b+2:]
s=q+"dot"
if s[len(s)-2:]=="at" and s[:3]!="dot" and s[:2]!="at":
t=s[:len(s)-2]
a=t.split('dot')
l=".".join(a)
b=l.find('at')
q=l[:b]+"@"+l[b+2:]
s=q+"at"
print(s)
else:
a=s.split('dot')
l=".".join(a)
b=l.find('at')
q=l[:b]+"@"+l[b+2:]
print(q)

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
from sys import stdin
input=stdin.readline
voiceEmail = input()
dotReplaced = voiceEmail[1:len(voiceEmail) - 2].replace('dot', '.')
voiceEmail = voiceEmail[0] + dotReplaced + voiceEmail[len(voiceEmail) - 2:]
atReplaced = voiceEmail[1:len(voiceEmail) - 2].replace('at', '@', 1)
voiceEmail = voiceEmail[0] + atReplaced + voiceEmail[len(voiceEmail) - 2:]
print(voiceEmail)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
import sys
from array import array # noqa: F401
def input():
return sys.stdin.buffer.readline().decode('utf-8')
s = input().rstrip()
ans = s[0]
suf = s[-1]
s = s[1:-1]
at_flag = 0
while s:
if s[:3] == 'dot':
ans += '.'
s = s[3:]
elif not at_flag and s[:2] == 'at':
ans += '@'
at_flag = 1
s = s[2:]
else:
ans += s[0]
s = s[1:]
print(ans + suf)

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
def main():
desc = input()
chunk = desc[1:-1]
chunk = chunk.replace("at", "@", 1)
chunk = chunk.replace("dot", ".")
print(desc[0] + chunk + desc[-1])
main()
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Tags: expression parsing, implementation
Correct Solution:
```
#!/bin/python
email = input()
m = {'@' : 'at', '.' : 'dot'}
replaced = ''
addAtLast = False
sep = []
def removeFirstLast(ch):
global replaced, addAtLast,sep, email
if m[ch] in email:
if sep[0] == '':
del sep[0]
replaced = m[ch] + sep[0]
else:
replaced = sep[0]
if len(sep)>0:
if sep[-1] == '':
del sep[-1]
addAtLast = True
else:
replaced = sep[0]
def addLast(ch) :
global replaced, addAtLast
if addAtLast :
replaced += m[ch]
#Code Starts from here :
#First replacing all the dots
sep = email.split(m['.'])
removeFirstLast('.')
for word in sep [1:]:
replaced += '.' + word
addLast('.')
#Next replacing all the ats
email = replaced
replaced = ''
addAtLast = False
sep = email.split(m['@'])
removeFirstLast('@')
#If there are more than 1 @ :
count = 0
for word in sep[1:] :
if count<1 :
replaced+= '@' + word
count+=1
else:
replaced+= 'at' + word
addLast('@')
print (replaced)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Submitted Solution:
```
s = input()
# don't start at first character!
# replace first occurance of 'at' with '@'
s = s[0] + s[1:].replace("at", "@", 1)
# replace the last 'dot' with '.'
s = s[0] + s[1:-1].replace("dot", ".") + s[-1]
print(s)
```
Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input

Submitted Solution:
```
m = input()
m = m.replace("at","@")
m = m.replace("dot",".")
if m[0] == ".":
m = "dot" + m[1:]
if m[-1] == ".":
m = m[:-1] + "dot"
if m[0] == "@":
m = "at" + m[1:]
if m.count("@") > 1:
n = m.find("@")
m = m[:n+1] + m[n+1:].replace("@","at")
print(m)
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Submitted Solution:
```
s = str(input())
s = s.replace("at","@")
s = s.replace("dot",".")
if s[0]==".":
s = "dot"+s[1:]
if s[0]=="@":
s = "at"+s[1:]
if s[len(s)-1]==".":
s = s[:len(s)-1]+"dot"
if s[len(s)-1]=="@":
s = s[:len(s)-1]+"at"
print(s)
```
No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Submitted Solution:
```
m = input()
m = m.replace("at","@")
m = m.replace("dot",".")
if m[0] == ".":
m = "dot" + m[1:]
if m[-1] == ".":
m = m[:-1] + "dot"
if m.count("@") > 1:
n = m.find("@")
m = m[:n+1] + m[n+1:].replace("@","at")
print(m)
```
No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input
vasyaatgmaildotcom
Output
vasya@gmail.com
Input
dotdotdotatdotdotat
Output
dot..@..at
Input
aatt
Output
a@t
Submitted Solution:
```
t = input()
t = t.replace("dot", '.')
t = t.replace("at", '@')
if t.find('.')==0: t = t.replace(".", "dot", 1)
if t.find('@')==0: t = t.replace("@", "at", 1)
if t.rfind('.')==len(t)-1:
t = t[0:len(t)-2]
t += "dot"
if t.rfind('@')==len(t)-1:
t = t[0:len(t)-1]
t += "at"
print(t)
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Sometimes one has to spell email addresses over the phone. Then one usually pronounces a dot as dot, an at sign as at. As a result, we get something like vasyaatgmaildotcom. Your task is to transform it into a proper email address (vasya@gmail.com).
It is known that a proper email address contains only such symbols as . @ and lower-case Latin letters, doesn't start with and doesn't end with a dot. Also, a proper email address doesn't start with and doesn't end with an at sign. Moreover, an email address contains exactly one such symbol as @, yet may contain any number (possible, zero) of dots.
You have to carry out a series of replacements so that the length of the result was as short as possible and it was a proper email address. If the lengths are equal, you should print the lexicographically minimal result.
Overall, two variants of replacement are possible: dot can be replaced by a dot, at can be replaced by an at.
Input
The first line contains the email address description. It is guaranteed that that is a proper email address with all the dots replaced by dot an the at signs replaced by at. The line is not empty and its length does not exceed 100 symbols.
Output
Print the shortest email address, from which the given line could be made by the described above replacements. If there are several solutions to that problem, print the lexicographically minimal one (the lexicographical comparison of the lines are implemented with an operator < in modern programming languages).
In the ASCII table the symbols go in this order: . @ ab...z
Examples
Input

Submitted Solution:
```
s=input()
i=s.count("at")
j=s.count("dot")
if( i != 1):
index=s.find("at")
index=index+3
s1=s[0:index]
s2=s[index:]
s2=s2.replace("at","@",i-1)
s=s1+s2
else:
s=s.replace("at","@")
if(j !=1):
ind=s.find("dot")
ind=ind+4
s3=s[0:ind]
s4=s[ind:]
s4=s4.replace("dot",".")
s=s3+s4
else:
s=s.replace("dot",".")
print(s)

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.
Examples
Input

Tags: implementation, strings
Correct Solution:
```
s=str(input())
if (s[0] == s[0].lower() and s[1:] == s[1:].upper()):
print(s[0].upper()+s[1:].lower())
elif (s == s.upper()):
print(s.lower())
else:
print(s)

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.
Examples
Input

Tags: implementation, strings
Correct Solution:
```
a = input()
if a.isupper() or a[1:].isupper() or (len(a)==1 and a.islower()):
a = list(a)
for i in range(len(a)):
if a[i].isupper():
a[i] = a[i].lower()
else:
a[i] = a[i].upper()
print("".join(a))

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.

Tags: implementation, strings
Correct Solution:
```
s=input().strip()
a=s
if len(s)==1:
if a.upper()==s:
print(a.lower())
else:
print(a.upper())
else:
if a.upper()==s:
print(a.lower())
else:
x=a[0].lower()
y=a[1:].upper()
if x==s[0] and y==s[1:]:
x=a[0].upper()
y=a[1:].lower()
print(x+y)
else:
print(s)
```

wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.

Correct Solution:
```
s=input()
if s.upper()==s:
print(s.lower())
else:
q=s[0]
i=s[1:]
if s[0]==q.lower() and i.upper()==i:
print(q.upper()+i.lower())
else:
print(s)

wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.
Examples
Input

Tags: implementation, strings
Correct Solution:
```
word = input()
if len(word)==1 and word.isupper():
print(word.lower())
elif len(word) ==1 and word.islower():
print(word.upper())
else:
if word[1:].isupper() and word[0].islower():
print(word.capitalize())
elif word.isupper():
print(word.lower())
else:
print(word)

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.

Tags: implementation, strings
Correct Solution:
```
n=input()
c=0
if n[0].islower()==True:
c+=1
for i in range(0,len(n)):
if n[i].isupper()==True:
c+=1
r=""
if len(n)==c:
for i in n:
if i.isupper()==True:
r+=i.lower()
else:
r+=i.upper()
print(r)
else:
print(n)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
wHAT DO WE NEED cAPS LOCK FOR?
Caps lock is a computer keyboard key. Pressing it sets an input mode in which typed letters are capital by default. If it is pressed by accident, it leads to accidents like the one we had in the first passage.
Let's consider that a word has been typed with the Caps lock key accidentally switched on, if:
* either it only contains uppercase letters;
* or all letters except for the first one are uppercase.
In this case we should automatically change the case of all letters. For example, the case of the letters that form words "hELLO", "HTTP", "z" should be changed.
Write a program that applies the rule mentioned above. If the rule cannot be applied, the program should leave the word unchanged.
Input
The first line of the input data contains a word consisting of uppercase and lowercase Latin letters. The word's length is from 1 to 100 characters, inclusive.
Output
Print the result of the given word's processing.
Examples

Tags: implementation, strings
Correct Solution:
```
#! /usr/bin/env python3
word = input()
if (word.isupper()) or (word[1:].isupper()) or len(word) == 1:
word = word.swapcase()
print(word)
else:
print(word)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Little penguin Polo adores strings. But most of all he adores strings of length n.
One day he wanted to find a string that meets the following conditions:
1. The string consists of n lowercase English letters (that is, the string's length equals n), exactly k of these letters are distinct.
2. No two neighbouring letters of a string coincide; that is, if we represent a string as s = s1s2... sn, then the following inequality holds, si ≠ si + 1(1 ≤ i < n).
3. Among all strings that meet points 1 and 2, the required string is lexicographically smallest.
Help him find such string or state that such string doesn't exist.
String x = x1x2... xp is lexicographically less than string y = y1y2... yq, if either p < q and x1 = y1, x2 = y2, ... , xp = yp, or there is such number r (r < p, r < q), that x1 = y1, x2 = y2, ... , xr = yr and xr + 1 < yr + 1. The characters of the strings are compared by their ASCII codes.
Input
A single line contains two positive integers n and k (1 ≤ n ≤ 106, 1 ≤ k ≤ 26) — the string's length and the number of distinct letters.
Output
In a single line print the required string. If there isn't such string, print "-1" (without the quotes).
Examples
Input
7 4
Output
ababacd
Input
4 7
Output
-1

Correct Solution:
```
n, k = map(int, input().split())
if k > n or k == 1 and n > 1:
print(-1)
elif k == 1 and n == 1:
print('a')
else:
print(('ab' * (n // 2 + 1))[: (n - (k - 2))] + 'cdefghijklmnopqrstuvwxyz'[:k - 2])
```

Provide tags and a correct Python 3 solution for this coding contest problem.
Little penguin Polo adores strings. But most of all he adores strings of length n.
One day he wanted to find a string that meets the following conditions:
1. The string consists of n lowercase English letters (that is, the string's length equals n), exactly k of these letters are distinct.
2. No two neighbouring letters of a string coincide; that is, if we represent a string as s = s1s2... sn, then the following inequality holds, si ≠ si + 1(1 ≤ i < n).
3. Among all strings that meet points 1 and 2, the required string is lexicographically smallest.
Help him find such string or state that such string doesn't exist.
String x = x1x2... xp is lexicographically less than string y = y1y2... yq, if either p < q and x1 = y1, x2 = y2, ... , xp = yp, or there is such number r (r < p, r < q), that x1 = y1, x2 = y2, ... , xr = yr and xr + 1 < yr + 1. The characters of the strings are compared by their ASCII codes.
Input
A single line contains two positive integers n and k (1 ≤ n ≤ 106, 1 ≤ k ≤ 26) — the string's length and the number of distinct letters.
Output
In a single line print the required string. If there isn't such string, print "-1" (without the quotes).
Examples
Input
7 4
Output
ababacd
Input
4 7
Output
-1

Correct Solution:
```

import sys
from io import BytesIO, IOBase
def main():
n, t = map(int, input().split())
alphas = "abcdefghijklmnopqrstuvwxyz"
if t > n:
print(-1)
elif n > 1 and t == 1:
print(-1)
elif n == 1 and t == 1:
print("a")
elif t == n:
print(alphas[:n])
else:
ans = ''
if (n-(t-2)) % 2 == 1:
ans += "ab"*((n-(t-2))//2)
ans += "a"
if t > 2:
ans += alphas[2:(t-2) + 2]
else:
ans += "ab"*((n-(t-2))//2)
if t > 2:
ans += alphas[2:(t-2) + 2]
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Little penguin Polo adores strings. But most of all he adores strings of length n.
One day he wanted to find a string that meets the following conditions:
1. The string consists of n lowercase English letters (that is, the string's length equals n), exactly k of these letters are distinct.
2. No two neighbouring letters of a string coincide; that is, if we represent a string as s = s1s2... sn, then the following inequality holds, si ≠ si + 1(1 ≤ i < n).
3. Among all strings that meet points 1 and 2, the required string is lexicographically smallest.
Help him find such string or state that such string doesn't exist.
String x = x1x2... xp is lexicographically less than string y = y1y2... yq, if either p < q and x1 = y1, x2 = y2, ... , xp = yp, or there is such number r (r < p, r < q), that x1 = y1, x2 = y2, ... , xr = yr and xr + 1 < yr + 1. The characters of the strings are compared by their ASCII codes.
Input
A single line contains two positive integers n and k (1 ≤ n ≤ 106, 1 ≤ k ≤ 26) — the string's length and the number of distinct letters.
Output
In a single line print the required string. If there isn't such string, print "-1" (without the quotes).
Examples
Input
7 4
Output
ababacd
Input
4 7
Output
-1
Tags: greedy
Correct Solution:
```
n, k = map(int, input().split())
if n < k or k > 26: print(-1)
elif k == 1: print('a' if n == 1 else -1)
else: print(('ab' * (n // 2 + 1))[: n - k + 2] + 'cdefghijklmnopqrstuvwxyz'[: k - 2])
