Provide tags and a correct Python 3 solution for this coding contest problem.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".

Correct Solution:
```
a = input()
print( max(a) * a.count(max(a)))
```

Provide tags and a correct Python 3 solution for this coding contest problem.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Tags: binary search, bitmasks, brute force, greedy, implementation, strings
Correct Solution:
```
#!/usr/bin/python3.5
s=input()
l=list(s)
l.sort()
k=l[-1]
for i in l[::-1]:
if i!=k:
break
else:
print(k,end='')

Provide tags and a correct Python 3 solution for this coding contest problem.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Tags: binary search, bitmasks, brute force, greedy, implementation, strings
Correct Solution:
```
y=input()
print( max(y)*y.count(max(y)) )
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input

Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:

res += s[i]
else:
break
return res
def main():
s = input()

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:
```
s = input()
m = max(s)
n = sum(map(lambda x: x==m, s))
print(m*n)
```
Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input

mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:
```
s=input()
max=0

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:
```
from itertools import chain, combinations
def fun(iterable):
lst = list(iterable)
return chain.from_iterable(combinations(lst, n) for n in range(len(lst) + 1))
s = input()
t = ''
for elem in fun(s):
x, y = ''.join(s), ''.join(s[::-1])
if x == y and x > t:
t = x
print(t)
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
This problem's actual name, "Lexicographically Largest Palindromic Subsequence" is too long to fit into the page headline.
You are given string s consisting of lowercase English letters only. Find its lexicographically largest palindromic subsequence.
We'll call a non-empty string s[p1p2... pk] = sp1sp2... spk (1 ≤ p1 < p2 < ... < pk ≤ |s|) a subsequence of string s = s1s2... s|s|, where |s| is the length of string s. For example, strings "abcb", "b" and "abacaba" are subsequences of string "abacaba".
String x = x1x2... x|x| is lexicographically larger than string y = y1y2... y|y| if either |x| > |y| and x1 = y1, x2 = y2, ..., x|y| = y|y|, or there exists such number r (r < |x|, r < |y|) that x1 = y1, x2 = y2, ..., xr = yr and xr + 1 > yr + 1. Characters in the strings are compared according to their ASCII codes. For example, string "ranger" is lexicographically larger than string "racecar" and string "poster" is lexicographically larger than string "post".
String s = s1s2... s|s| is a palindrome if it matches string rev(s) = s|s|s|s| - 1... s1. In other words, a string is a palindrome if it reads the same way from left to right and from right to left. For example, palindromic strings are "racecar", "refer" and "z".
Input
The only input line contains a non-empty string s consisting of lowercase English letters only. Its length does not exceed 10.
Output
Print the lexicographically largest palindromic subsequence of string s.
Examples
Input
radar
Output
rr
Input
bowwowwow
Output
wwwww
Input
codeforces
Output
s
Input
mississipp
Output
ssss
Note
Among all distinct subsequences of string "radar" the following ones are palindromes: "a", "d", "r", "aa", "rr", "ada", "rar", "rdr", "raar" and "radar". The lexicographically largest of them is "rr".
Submitted Solution:
```
s = input()
lista = []
for i in s:
lista.append(i)
for i in range(len(s)):
for j in range(i+1, len(s)):
lista.append(s[i]+s[j])
for k in range(j+1, len(s)):
lista.append(s[i]+s[j]+s[k])
for p in range(k+1, len(s)):
lista.append(s[i]+s[j]+s[k]+s[p])
for m in range(p+1, len(s)):
lista.append(s[i]+s[j]+s[k]+s[p]+s[m])
for n in range(m+1, len(s)):
lista.append(s[i]+s[j]+s[k]+s[p]+s[m]+s[n])
for o in range(n+1, len(s)):
lista.append(s[i]+s[j]+s[k]+s[p]+s[m]+s[n]+s[o])
for w in range(o+1, len(s)):
lista.append(s[i]+s[j]+s[k]+s[p]+s[m]+s[n]+s[o]+s[w])
lista.sort()
print(lista[-1])

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

def dfs(i, j):
if a[i][j] != -1:
return a[i][j]
d1 = dfs(i - 1, j - 1) + (s1[i - 1] == s2[j - 1]) * s1[i - 1]
d2 = dfs(i - 1, j)
d3 = dfs(i, j - 1)
a[i][j] = max(d1, d2, d3, key=lambda x: [len(x), -x.count(virus)])
return a[i][j]
s1, s2, virus = input(), input(), input()
#s1, s2, virus = 'SLO', 'LL', 'asda'
n1, n2 = len(s1), len(s2)
a = [[''] * (n2 + 1)] + [[''] + [-1] * n2 for i in range(n1)]
#a[1][0] = 'hjkhj'
ans = dfs(n1, n2)
while virus in ans:
ans = min(ans.replace(virus, virus[:-1]), ans.replace(virus, virus[1:]), key=lambda x: x.count(virus))
print(0 if ans == '' else ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

for i in range(v - 1):
j = v - i - 2
while j > 0:

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

t[i][j] = max(s, g(i - 1, j), g(i, j - 1), key=lambda q: len(q) - q.count(v))
return t[i][j]
s = g(len(a) - 1, len(b) - 1)
while v in s: s = min(s.replace(v, v[:-1]), s.replace(v, v[1:]), key=lambda q: q.count(v))
print(s if s else 0)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
In mathematics, a subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements. For example, the sequence BDF is a subsequence of ABCDEF. A substring of a string is a continuous subsequence of the string. For example, BCD is a substring of ABCDEF.
You are given two strings s1, s2 and another string called virus. Your task is to find the longest common subsequence of s1 and s2, such that it doesn't contain virus as a substring.
Input
The input contains three strings in three separate lines: s1, s2 and virus (1 ≤ |s1|, |s2|, |virus| ≤ 100). Each string consists only of uppercase English letters.
Output
Output the longest common subsequence of s1 and s2 without virus as a substring. If there are multiple answers, any of them will be accepted.
If there is no valid common subsequence, output 0.

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
n=int(input())
s=input()
a=[int(o) for o in input().split()]
dp=[[0 for i in range(5)] for j in range(n+1)]
for i in range(n+1):
dp[i][4]=float('inf')
word=list("hard")
di={"h":0,"a":1,"r":2,"d":3}
for i in range(1,n+1):
dp[i][0]=dp[i-1][0]
dp[i][1]=dp[i-1][1]
dp[i][2]=dp[i-1][2]
dp[i][3]=dp[i-1][3]
if s[i-1] in word:
dp[i][di[s[i-1]]]=min(a[i-1]+dp[i][di[s[i-1]]],dp[i][di[s[i-1]]-1])
print(min(dp[n]))

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
a = [0 for i in range(100010)]
dp = [[0 for i in range(4)] for j in range(100010)]
ans = 1e18
t = "hard"
n = int(input())
s = input()
s = ' ' + s
for i in range(n+1):
for j in range(4):
dp[i][j] = 1e18
dp[0][0] = 0
a = [0] + list(map(int, input().split()))
for x in a:
dp[0][0] += x
for i in range(1, n+1):
p = t.find(s[i])
for j in range(4):
if j==p:
if j<3:
dp[i][j+1] = min(dp[i][j+1], dp[i-1][j] - a[i])
dp[i][j] = min(dp[i][j], dp[i-1][j])
else:
dp[i][j] = min(dp[i][j], dp[i-1][j] - a[i])
for i in range(4):
ans = min(ans, dp[n][i])
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

print(*args, file=sys.stderr, **kwargs)
n = int(input())
s = input()
ambiguity = list(map(int, input().split()))
s_a = [y for y in list(zip([x for x in s], ambiguity)) if y[0] in "hard"]
if(len(s_a) < 4):
print(0)
quit()
l = len(s_a)+1
h = [0]*l
ha = [0]*l
har = [0]*l
hard = [0]*l
last_a = -1
last_r = -1
last_d = -1
for i, (c,a) in enumerate(s_a):
if c == 'h':
h[i] = a + h[i-1]
else:

if c == 'd':
hard[i] = min(har[i], a+hard[last_d])
last_d = i
else:
hard[i] = hard[i-1]
eprint(h)
eprint(ha)
eprint(har)
eprint(hard)
print(hard[-2])

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
n=int(input())
s=input()
a=list(map(int,input().split()))
h=[0]*n
ha=[0]*n
har=[0]*n
hard=[0]*n
if s[0]=="h":
h[0]=a[0]
for i in range(1,n):
if s[i]=="h":
h[i]=h[i-1]+a[i]
ha[i]=ha[i-1]
har[i]=har[i-1]
hard[i]=hard[i-1]
elif s[i]=="a":
h[i]=h[i-1]
ha[i]=min(ha[i-1]+a[i],h[i])
har[i]=har[i-1]
hard[i]=hard[i-1]
elif s[i]=="r":
h[i]=h[i-1]
ha[i]=ha[i-1]
har[i]=min(har[i-1]+a[i],ha[i],h[i])
hard[i]=hard[i-1]
elif s[i]=="d":
h[i]=h[i-1]
ha[i]=ha[i-1]
har[i]=har[i-1]
hard[i]=min(hard[i-1]+a[i],h[i],ha[i],har[i])
else:
h[i]=h[i-1]
ha[i]=ha[i-1]
har[i]=har[i-1]
hard[i]=hard[i-1]
print(hard[-1])

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
n = int(input())
s = input()
arr = list(map(int, input().split()))
dp = {}
for i in range(n):
dp[i] = {}
for j in range(4):
if i == 0 and j == 0:
if s[i] == 'h': dp[i][j] = arr[i]
else: dp[i][j] = 0
elif i == 0: dp[i][j] = 0
elif j == 0:
dp[i][j] = dp[i - 1][j]
if s[i] == 'h': dp[i][j] += arr[i]
elif j == 1:
if s[i] != 'a': dp[i][j] = dp[i - 1][j]
else: dp[i][j] = min(arr[i] + dp[i - 1][j], dp[i - 1][j - 1])
elif j == 2:
if s[i] != 'r': dp[i][j] = dp[i - 1][j]
else: dp[i][j] = min(arr[i] + dp[i - 1][j], dp[i - 1][j - 1])
else:
if s[i] != 'd': dp[i][j] = dp[i - 1][j]
else: dp[i][j] = min(arr[i] + dp[i - 1][j], dp[i - 1][j - 1])
print(dp[n - 1][3])

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
n = int(input())
s = input()
A = list(map(int, input().split()))
t = 'hard'
dph = [0] * (n + 1)
for i in range(n):
dph[i + 1] = dph[i] + A[i] * (s[i] == 'h')
dpha = [0] * (n + 1)
for i in range(n):
if s[i] != 'a':
dpha[i + 1] = dpha[i]
else:
dpha[i + 1] = min(dpha[i] + A[i], dph[i])
dphar = [0] * (n + 1)
for i in range(n):
if s[i] != 'r':
dphar[i + 1] = dphar[i]
else:
dphar[i + 1] = min(dphar[i] + A[i], dpha[i])
dphard = [0] * (n + 1)
for i in range(n):
if s[i] != 'd':
dphard[i + 1] = dphard[i]
else:
dphard[i + 1] = min(dphard[i] + A[i], dphar[i])
print(dphard[-1])

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Provide tags and a correct Python 3 solution for this coding contest problem.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output
5
Input
8
hhzarwde
3 2 6 9 4 8 7 1
Output
4
Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Correct Solution:
```
import math
n = int(input())
s = input()
c = list(map(int, input().split()))
h = [0]*n
ta = 0
tr = 0
td = 0
for i in range(n):
if s[i]=='h':
h[i] = c[i]
if(i):
h[i] = h[i] + h[i-1]
if s[i]=='a':
ta = min(ta+c[i], h[i])
elif s[i]=='r':
tr = min(tr+c[i], ta)
elif s[i]=='d':
td = min(td+c[i], tr)
print(td)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples

Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.
Submitted Solution:
```
n = int(input())
s = input()
t = 'hard'
a = list(map(int, input().split()))
dp = [x[:] for x in [[0]*4]*(n+1)]
for i in range(1,n+1):
for j in range(4):
if s[i-1] == t[j]:
if j ==0:
dp[i][j] = dp[i-1][j]+a[i-1]
else:
dp[i][j] = min(dp[i-1][j]+a[i-1], dp[i-1][j-1])
else:
dp[i][j] = dp[i-1][j]
res = float('inf')
for i in range(4):
res = min(res, dp[n][i])
print(res)
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.

Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input

Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.
Submitted Solution:
```
input()
dp = [0] * 5
for i, c in zip(map('hard'.find, input()), map(int, input().split())) :
if i < 0 : continue
dp[i+1] = min(dp[i+1], dp[i])
dp[i] += c
# print('hard'[i],dp)
print(min(dp[:-1]))
```
Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.

Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples

Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input
6
hhardh
3 2 9 11 7 1
Output

Input
6
hhaarr
1 2 3 4 5 6
Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples

Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Vasya is preparing a contest, and now he has written a statement for an easy problem. The statement is a string of length n consisting of lowercase Latin latters. Vasya thinks that the statement can be considered hard if it contains a subsequence hard; otherwise the statement is easy. For example, hard, hzazrzd, haaaaard can be considered hard statements, while har, hart and drah are easy statements.
Vasya doesn't want the statement to be hard. He may remove some characters from the statement in order to make it easy. But, of course, some parts of the statement can be crucial to understanding. Initially the ambiguity of the statement is 0, and removing i-th character increases the ambiguity by a_i (the index of each character is considered as it was in the original statement, so, for example, if you delete character r from hard, and then character d, the index of d is still 4 even though you delete it from the string had).
Vasya wants to calculate the minimum ambiguity of the statement, if he removes some characters (possibly zero) so that the statement is easy. Help him to do it!
Recall that subsequence is a sequence that can be derived from another sequence by deleting some elements without changing the order of the remaining elements.
Input
The first line contains one integer n (1 ≤ n ≤ 10^5) — the length of the statement.
The second line contains one string s of length n, consisting of lowercase Latin letters — the statement written by Vasya.
The third line contains n integers a_1, a_2, ..., a_n (1 ≤ a_i ≤ 998244353).
Output
Print minimum possible ambiguity of the statement after Vasya deletes some (possibly zero) characters so the resulting statement is easy.
Examples
Input

Output
0
Note
In the first example, first two characters are removed so the result is ardh.
In the second example, 5-th character is removed so the result is hhzawde.
In the third example there's no need to remove anything.
Submitted Solution:
```
if __name__ == '__main__':
n = int(input())
s = list(input())
v = list(map(int, input().rstrip().split()))
i = 0
hard = list('hard$')
val = [0,0,0,0]
c = 0
while c < 4 and i < n:
if s[i] == hard[c + 1]:
c += 1
if s[i] == hard[c]:
val[c] += v[i]
i += 1
print (min(val))

Provide tags and a correct Python 3 solution for this coding contest problem.
This is an interactive problem. Remember to flush your output while communicating with the testing program. You may use fflush(stdout) in C++, system.out.flush() in Java, stdout.flush() in Python or flush(output) in Pascal to flush the output. If you use some other programming language, consult its documentation. You may also refer to the guide on interactive problems: <https://codeforces.com/blog/entry/45307>.
You are given a string t consisting of n lowercase Latin letters. This string was cyphered as follows: initially, the jury had a string s consisting of n lowercase Latin letters. Then they applied a sequence of no more than n (possibly zero) operations. i-th operation is denoted by two integers a_i and b_i (1 ≤ a_i, b_i ≤ n), and means swapping two elements of the string with indices a_i and b_i. All operations were done in the order they were placed in the sequence. For example, if s is xyz and 2 following operations are performed: a_1 = 1, b_1 = 2; a_2 = 2, b_2 = 3, then after the first operation the current string is yxz, and after the second operation the current string is yzx, so t is yzx.
You are asked to restore the original string s. Unfortunately, you have no information about the operations used in the algorithm (you don't even know if there were any operations in the sequence). But you may run the same sequence of operations on any string you want, provided that it contains only lowercase Latin letters and its length is n, and get the resulting string after those operations.
Can you guess the original string s asking the testing system to run the sequence of swaps no more than 3 times?
The string s and the sequence of swaps are fixed in each test; the interactor doesn't try to adapt the test to your solution.
Input
Initially the testing system sends one string t, consisting of lowercase Latin letters (1 ≤ |t| = n ≤ 10^4).
Output
To give the answer, your program should print one line ! s with a line break in the end. After that, it should flush the output and terminate gracefully.
Interaction
Before giving the answer, you may submit no more than 3 queries. To ask a query, print one line in the following format: ? s', where s' should be a string consisting of exaclty n lowercase Latin letters. The line should be ended with a line break character. After submitting a query, flush the output and read the answer to your query — a string t' consisting of n lowercase Latin letters, which is the result of applying the sequence of swaps to string s'. This string will be given on a separate line ended by a line break character.
If you submit an incorrect query (or ask more than 3 queries), the answer to it will be one string 0. After receiving such an answer, your program should terminate immediately — otherwise you may receive verdict "Runtime error", "Time limit exceeded" or some other verdict instead of "Wrong answer".
Example
Input
yzx
aab
baa
aba
Output
? baa
? aba
? aab
! xyz
Note
In the sample, the testcase described in the statement is used. The participant asks the first query with string baa, which is transformed to aab. The second query contains string aba, which is transformed to baa. The third query contains string aab, which is transformed to aba. The participant can deduce that the initial string s was xyz.
Note for hacking phase:
To submit a test in hacking phase, you should provide it in the following format:
The first line should contain the string s you guess, consisting of n ∈ [1, 10000] lowercase Latin letters.
The second line should contain k (0 ≤ k ≤ n) — the number of swap operations in the sequence.
Then k lines should follow, i-th of them should denote i-th operation with two integers a_i and b_i (1 ≤ a_i, b_i ≤ n).
For example, the sample test would look like that:
xyz
2
1 2
2 3

Correct Solution:
```
from itertools import chain, cycle, islice, repeat
from operator import itemgetter
d = 26
a = ord('a')
t = input()
n = len(t)
p = [0]*n
for b in (d ** 2, d, 1):
if n >= b:
q = (repeat(chr(a + i), b) for i in range(d))
q = chain.from_iterable(q)
q = cycle(q)
q = islice(q, n)
q = ''.join(q)
print('?', q, flush=True)
s = input()
for i, c in enumerate(s):
p[i] += b * (ord(c) - a)
p = zip(range(n), p)
p = sorted(p, key=itemgetter(1))
p = next(zip(*p))
ans = list(t)
ans = ''.join(ans[p[i]] for i in range(n))
print('!', ans, flush=True)

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
A string is called diverse if it contains consecutive (adjacent) letters of the Latin alphabet and each letter occurs exactly once. For example, the following strings are diverse: "fced", "xyz", "r" and "dabcef". The following string are not diverse: "az", "aa", "bad" and "babc". Note that the letters 'a' and 'z' are not adjacent.
Formally, consider positions of all letters in the string in the alphabet. These positions should form contiguous segment, i.e. they should come one by one without any gaps. And all letters in the string should be distinct (duplicates are not allowed).
You are given a sequence of strings. For each string, if it is diverse, print "Yes". Otherwise, print "No".
Input
The first line contains integer n (1 ≤ n ≤ 100), denoting the number of strings to process. The following n lines contains strings, one string per line. Each string contains only lowercase Latin letters, its length is between 1 and 100, inclusive.
Output
Print n lines, one line per a string in the input. The line should contain "Yes" if the corresponding string is diverse and "No" if the corresponding string is not diverse. You can print each letter in any case (upper or lower). For example, "YeS", "no" and "yES" are all acceptable.

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
n, m = map(int, input().split())
s = input()
sl = len(s)
if m:
y = map(int, input().split())
else:
y = []
def prefix_func(s):
pi = [0] * len(s)
for i in range(1, len(s)):
j = pi[i - 1]
while j > 0 and s[i] != s[j]:
j = pi[j - 1]
pi[i] = j + 1 if s[i] == s[j] else j
return pi
pi = prefix_func(s)
good = [False] * sl
j = sl - 1
while j >= 0:
good[j] = True
j = pi[j] - 1
end = 0
s = 0
# print good
for x in y:
if x > end:
s += x - end - 1
else:
if not good[end - x]:
print('0')
exit()
end = x + sl - 1
s += max(0, n - end)
print (pow(26, s, 1000000007))

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
# -*- coding: utf-8 -*-
def solve():
n, m = map(int, input().split())
p = input()
if m == 0:
return powmod(n)
delta = len(p) - 1
ys = map(int, input().split())
tail = 0
free_chars = 0
for y in ys:
if y > tail:
free_chars += y - tail - 1
elif not is_consistent(p, tail - y + 1):
return 0
tail = y + delta
free_chars += n - tail
return powmod(free_chars)
ok_set = set()
def is_consistent(p, margin):
global ok_set
if margin in ok_set:
return True
elif p[:margin] == p[-margin:]:
ok_set.add(margin)
return True
else:
return False
def powmod(p):
mod = 10**9 + 7
pbin = bin(p)[2:][-1::-1]
result = 26 if pbin[0] == '1' else 1
tmp = 26
for bit in pbin[1:]:
tmp *= tmp
tmp %= mod
if bit == '1':
result *= tmp
result %= mod
return result
print(solve())

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
import sys
def prefix(s):
m = len(s)
v = [0]*len(s)
for i in range(1,len(s)):
k = v[i-1]
while k > 0 and s[k] != s[i]:
k = v[k-1]
if s[k] == s[i]:
k = k + 1
v[i] = k
w = set()
i = m-1
while v[i] != 0:
w.add(m-v[i])
i = v[i]-1
return w
n,m = map(int, input().split())
if m == 0:
print(pow(26, n, 1000000007))
sys.exit(0)
p = input()
l = len(p)
x = list(map(int,input().split()))
w = prefix(p)
busy = l
for i in range(1,m):
if x[i]-x[i-1] < l and (x[i] - x[i-1]) not in w:
print(0)
sys.exit(0)
busy += min(x[i]-x[i-1], l)
print(pow(26,n-busy, 1000000007))

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
def preZ(s): #preprocessing by Z algo
n = len(s)
z = [0]*n
z[0] = n
r = 0
if n==1: return z
while r+1<n and s[r]==s[r+1]: r+=1
z[1] = r #note z=length! not 0-indexed
l = 1 if r>0 else 0
for k in range(2,n):
bl = r+1-k #|\beta|
gl = z[k-l] #|\gamma|
if gl<bl:
z[k]=z[k-l] #Case2a
else:
j=max(0,r-k+1) #Case1 & 2b
while k+j<n and s[j]==s[k+j]: j+=1
z[k]=j
l,r =k,k+j-1
return z

fc = l[0]-1
for i in range(1,len(l)):
r = l[i-1]+m
if l[i]>r:
fc += l[i]-r
continue
if l[i]<r and l[i]-l[i-1] not in s:
return 0
fc += n-(l[-1]+m-1)
return binpow(26,fc)
n,m = list(map(int,input().split()))

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
# -*- coding: utf-8 -*-
def solve():
n, m = map(int, input().split())
p = input()
if m == 0:
return powmod(n)
delta = len(p) - 1
ys = map(int, input().split())
tail = 0
free_chars = 0
for y in ys:
if y > tail:

elif not is_consistent(p, tail - y + 1):
return 0
tail = y + delta
free_chars += n - tail
return powmod(free_chars)

def powmod(p):
mod = 10**9 + 7
pbin = bin(p)[2:][-1::-1]
result = 26 if pbin[0] == '1' else 1
tmp = 26
for bit in pbin[1:]:
tmp *= tmp
tmp %= mod
if bit == '1':
result *= tmp
result %= mod
return result

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output

Input
5 2

Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Provide tags and a correct Python 3 solution for this coding contest problem.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Correct Solution:
```
# -*- coding: utf-8 -*-
def solve():
mod = 10**9 + 7
n, m = map(int, input().split())
p = input()
if m == 0:
return powmod(n)

ys = map(int, input().split())
answer = 1
tail = 0
for y in ys:
if y > tail:

answer %= mod
elif not is_consistent(p, tail - y + 1):

pbin = bin(p)[2:][-1::-1]
result = 26 if pbin[0] == '1' else 1
tmp = 26
for bit in pbin[1:]:
tmp *= tmp
tmp %= mod
if bit == '1':
result *= tmp
result %= mod
return result
print(solve())

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).
Submitted Solution:
```
import sys
n, m = map(int, str(input()).split(" "))
p = str(input())
l = map(int, str(input()).split(" "))

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi

Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.

Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Tavas is a strange creature. Usually "zzz" comes out of people's mouth while sleeping, but string s of length n comes out from Tavas' mouth instead.
<image>
Today Tavas fell asleep in Malekas' place. While he was sleeping, Malekas did a little process on s. Malekas has a favorite string p. He determined all positions x1 < x2 < ... < xk where p matches s. More formally, for each xi (1 ≤ i ≤ k) he condition sxisxi + 1... sxi + |p| - 1 = p is fullfilled.
Then Malekas wrote down one of subsequences of x1, x2, ... xk (possibly, he didn't write anything) on a piece of paper. Here a sequence b is a subsequence of sequence a if and only if we can turn a into b by removing some of its elements (maybe no one of them or all).
After Tavas woke up, Malekas told him everything. He couldn't remember string s, but he knew that both p and s only contains lowercase English letters and also he had the subsequence he had written on that piece of paper.
Tavas wonders, what is the number of possible values of s? He asked SaDDas, but he wasn't smart enough to solve this. So, Tavas asked you to calculate this number for him.
Answer can be very large, so Tavas wants you to print the answer modulo 109 + 7.
Input
The first line contains two integers n and m, the length of s and the length of the subsequence Malekas wrote down (1 ≤ n ≤ 106 and 0 ≤ m ≤ n - |p| + 1).
The second line contains string p (1 ≤ |p| ≤ n).
The next line contains m space separated integers y1, y2, ..., ym, Malekas' subsequence (1 ≤ y1 < y2 < ... < ym ≤ n - |p| + 1).
Output
In a single line print the answer modulo 1000 000 007.
Examples
Input
6 2
ioi
1 3
Output
26
Input
5 2
ioi
1 2
Output
0
Note
In the first sample test all strings of form "ioioi?" where the question mark replaces arbitrary English letter satisfy.
Here |x| denotes the length of string x.
Please note that it's possible that there is no such string (answer is 0).

Provide a correct Python 3 solution for this coding contest problem.
We have a string s consisting of lowercase English letters. Snuke can perform the following operation repeatedly:
* Insert a letter `x` to any position in s of his choice, including the beginning and end of s.
Snuke's objective is to turn s into a palindrome. Determine whether the objective is achievable. If it is achievable, find the minimum number of operations required.
Constraints
* 1 \leq |s| \leq 10^5
* s consists of lowercase English letters.
Input
Input is given from Standard Input in the following format:
s
Output
If the objective is achievable, print the number of operations required. If it is not, print `-1` instead.
Examples

"Correct Solution:
```
s = input()
t= "".join(c for c in s if c!="x")
if t!=t[::-1]:
print(-1)
else:
ans=0
i=0
j=0
l=len(s)
while i+j<l-1:
if s[i] != s[l-1-j]:
ans+=1
if s[i] == "x" : i+=1
else : j+=1
else:
i+=1
j+=1
print(ans)

Provide a correct Python 3 solution for this coding contest problem.
We have a string s consisting of lowercase English letters. Snuke can perform the following operation repeatedly:
* Insert a letter `x` to any position in s of his choice, including the beginning and end of s.
Snuke's objective is to turn s into a palindrome. Determine whether the objective is achievable. If it is achievable, find the minimum number of operations required.
Constraints
* 1 \leq |s| \leq 10^5
* s consists of lowercase English letters.
Input
Input is given from Standard Input in the following format:
s
Output
If the objective is achievable, print the number of operations required. If it is not, print `-1` instead.

s=s.replace("x","")
if s[:len(s)//2]!=s[:-(len(s)//2)-1:-1]:
print(-1)
quit()
r=0
l=len(S)-1
ans=0
while r<l:
R,L=0,0
while S[r+R]=="x":
R+=1
while S[l-L]=="x":
L+=1
ans+=abs(R-L)
r+=R+1
l-=L+1
print(ans)

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
n = int(input())
a = []
for i in range(2*n-2):
a.append(input())
S = ''
P = ''
Lnm1 = []
Lnm2 = []
ans = []
for i in a:
if len(i) == n-1:
Lnm1.append(i)
elif len(i) == n-2:
Lnm2.append(i)
flag = 0
if n == 2:
print("PS")
elif n == 1:
print("P")
else:
S = Lnm2[0]
P = Lnm2[1]
if (Lnm2[0] == Lnm1[0][:n-2] and Lnm2[1] == Lnm1[1][1:]):
S = Lnm1[0]
P = Lnm1[1]
elif (Lnm2[1] == Lnm1[0][:n-2] and Lnm2[0] == Lnm1[1][1:]):
S = Lnm1[0]
P = Lnm1[1]
else:
S = Lnm1[1]
P = Lnm1[0]
flag = [0 for i in range(n)]
for i in a:
if flag[len(i)] == 0:
if len(i) <= len(P):
if i == S[:len(i)]:
ans.append("P")
flag[len(i)] = 'S'
else:
ans.append('S')
flag[len(i)] = 'P'
else:
ans.append(flag[len(i)])
print(*ans, sep = "")

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
n=int(input())
k=2*n-2
a=[]
b=[]
c=[]
for i in range(k):
s=input()
a.append(s)
c.append(s)
a.sort()
for i in range(k):
if(len(a[i])==n-1):
b.append(a[i])
s1=b[0][1:n-1]
s2=b[1][0:n-2]
if(s1==s2):
x=b[0][0]
p=b[0]
su=b[1]
else:
x=b[1][0]
p=b[1]
su=b[0]
cnt=[1]*n
p1=0;
res=[]
rest=[]
for i in range(k):
l=len(c[i])
if(cnt[l]==1 and c[i]==p[0:l]):
cnt[l]=0
res.append("P")
p1+=1
else:
cnt[l]=1
res.append("S")
if(p1==n-1):
print("".join(res))
else:
cnt=[1]*n
for i in range(k):
l=len(c[i])
if(cnt[l]==1 and c[i]==su[0:l]):
cnt[l]=0
rest.append("P")
p1+=1
else:
cnt[l]=1
rest.append("S")
print("".join(rest))

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
for _ in range(1):
n = int(input())
limit = (2*n)-2
ind = {}
e = {}
d = {}
for i in range(1,limit+1):
s = input()
if len(s) in d:
d[len(s)].append(s)
else:
d[len(s)] = [s]
if s in ind:
ind[s].append(i)
else:
ind[s] = [i]
if s in e:
e[s] += 1
else:
e[s] = 1
candidates = [d[n-1][0]+d[1][0],d[n-1][0]+d[1][1],d[n-1][1]+d[1][0],d[n-1][1]+d[1][1],d[1][0]+d[n-1][0],d[1][1]+d[n-1][0],d[1][0]+d[n-1][1],d[1][1]+d[n-1][1]]
for i in candidates:
te = {}
tind = {}
# print(i)
for j in e:
te[j] = e[j]
for j in ind:
tind[j] = ind[j].copy()
flag = 1
ans = ["Z"]*(limit+1)
for j in range(n-1):
w = i[0:j+1]
if w not in tind:
flag = 0
break
if len(tind[w]) == 0:
flag = 0
break
ans[tind[w].pop()] = "P"
if w in te:
te[w] -= 1
if te[w] == 0:
del te[w]
else:
flag = 0
break
i = i[::-1]
for j in range(n-1):
w = i[0:j+1][::-1]
if w not in tind:
flag = 0
break
if len(tind[w]) == 0:
flag = 0
break
ans[tind[w].pop()] = "S"
if w in te:
te[w] -= 1
if te[w] == 0:
del te[w]
else:
flag = 0
break
if flag:
print("".join(ans[1:]))
exit()

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
n = int(input())
a = [input() for i in range(2*n - 2)]
sorted_a = sorted(a, key=len, reverse=True)
guess = sorted_a[0] + sorted_a[1][-1]
guess2 = sorted_a[1] + sorted_a[0][-1]
check = [0]* len(a)
for i in range(0,len(a),2):
if(not((guess.startswith(sorted_a[i]) and guess.endswith(sorted_a[i+1])) or (guess.startswith(sorted_a[1+i]) and guess.endswith(sorted_a[i])))):
guess = guess2
break
for word in a:
if guess.startswith(word):
if check[len(word)] == 0:
print('P', end='')
check[len(word)] = 1
else:
print('S', end='')
else:
print('S', end='')

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples
Input
5
ba
a
abab
a
aba
baba
ab
aba
Output
SPPSPSPS
Input
3
a
aa
aa
a
Output
PPSS
Input
2
a
c
Output
PS
Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
from collections import namedtuple
SPos = namedtuple("SPos", "string, pos")
n = int(input())
levels = [[] for _ in range(n)]
for i in range(2 * n - 2):
s = input()
levels[len(s)].append(SPos(string=s, pos=i))
checkpoint = 1
for i in range(2, n):
# Try to see if anything fits
if levels[i][0].string[:-1] == levels[i - 1][0].string and \
levels[i][1].string[1:] == levels[i - 1][1].string:
pass
elif levels[i][1].string[:-1] == levels[i - 1][0].string and \
levels[i][0].string[1:] == levels[i - 1][1].string:
# Swap the order in the case of the current level
levels[i][0], levels[i][1] = levels[i][1], levels[i][0]
else:
# Change the order of everything beneath
for j in range(i - 1, checkpoint - 1, -1):
if not(levels[j + 1][0].string[:-1] == levels[j][0].string and \
levels[j + 1][1].string[1:] == levels[j][1].string):
levels[j][0], levels[j][1] = levels[j][1], levels[j][0]
# Recheck the current level
if not(levels[i][0].string[:-1] == levels[i - 1][0].string and \
levels[i][1].string[1:] == levels[i - 1][1].string):
levels[i][0], levels[i][1] = levels[i][1], levels[i][0]
checkpoint = i
result = ['' for _ in range(2 * n - 2)]
for level in levels[1:]:
result[level[0].pos] = 'P'
result[level[1].pos] = 'S'
print(''.join(result))

Provide tags and a correct Python 3 solution for this coding contest problem.
Ivan wants to play a game with you. He picked some string s of length n consisting only of lowercase Latin letters.
You don't know this string. Ivan has informed you about all its improper prefixes and suffixes (i.e. prefixes and suffixes of lengths from 1 to n-1), but he didn't tell you which strings are prefixes and which are suffixes.
Ivan wants you to guess which of the given 2n-2 strings are prefixes of the given string and which are suffixes. It may be impossible to guess the string Ivan picked (since multiple strings may give the same set of suffixes and prefixes), but Ivan will accept your answer if there is at least one string that is consistent with it. Let the game begin!
Input
The first line of the input contains one integer number n (2 ≤ n ≤ 100) — the length of the guessed string s.
The next 2n-2 lines are contain prefixes and suffixes, one per line. Each of them is the string of length from 1 to n-1 consisting only of lowercase Latin letters. They can be given in arbitrary order.
It is guaranteed that there are exactly 2 strings of each length from 1 to n-1. It is also guaranteed that these strings are prefixes and suffixes of some existing string of length n.
Output
Print one string of length 2n-2 — the string consisting only of characters 'P' and 'S'. The number of characters 'P' should be equal to the number of characters 'S'. The i-th character of this string should be 'P' if the i-th of the input strings is the prefix and 'S' otherwise.
If there are several possible answers, you can print any.
Examples

Note
The only string which Ivan can guess in the first example is "ababa".
The only string which Ivan can guess in the second example is "aaa". Answers "SPSP", "SSPP" and "PSPS" are also acceptable.
In the third example Ivan can guess the string "ac" or the string "ca". The answer "SP" is also acceptable.

Correct Solution:
```
n = int(input())
a = []
fe = -1
se = -1
for i in range(2*n - 2):
s = input()
if len(s) == n - 1:
if fe == -1:
fe = i
else:
se = i
a.append(s)
fl = True
s = a[fe] + a[se][-1]
b = [''] * len(a)
pr = [False] * n
su = [False] * n
for i in range(len(a)):
#pr
flp = False
ss = a[i]
if not pr[len(ss) - 1]:
if s[:len(ss)] == ss:
b[i] = 'P'
pr[len(ss) - 1] = True
flp = True
if not flp:
if not su[-len(ss)]:
if s[-len(ss):] == ss:
b[i] = 'S'
su[-len(ss)] = True
flp = True
if not flp:
fl = False
break
if not fl:
s = a[se] + a[fe][-1]
pr = [False] * n
su = [False] * n
for i in range(len(a)):
#pr
flp = False
ss = a[i]
if not pr[len(ss) - 1]:
if s[:len(ss)] == ss:
b[i] = 'P'
pr[len(ss) - 1] = True
flp = True
if not flp:
if not su[-len(ss)]:
if s[-len(ss):] == ss:
b[i] = 'S'
su[-len(ss)] = True
flp = True
for i in b:
print(i, end = '')

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
n, k = [int(x) for x in input().split()]
if k == 1:
print("1" + "0"*(n-1))
elif 3*k <= n:
# print("2")
print(("0" * ((n-k)//2)) + "1" + ("0"*(k-2)) + "1" + "0" * ((n-k)//2))
else:
tmp = "0" * ((n-k)//2) + "1"
s = tmp
s = tmp * (n // len(tmp) + 1)
s = s[:n]
print(s)

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
N, K = map(int, input().split())
if N == K:
print("0"*N)
elif K == 1:
print("0"*(N-1) + "1")
elif K == 3:
print("1" + "0"*(N-4) + "101")
else:
res = ["0"]*N
for i in range(0, N, N//2-K//2+1):
res[i] = "1"
print(''.join(res))

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Tags: constructive algorithms, math, strings
Correct Solution:
```
n, k = map( int, input().split() )
d = n - k
d = d // 2
l = []
while n > 0:
i = min(n,d)
while i>0:
l.append('1')
i -= 1
n -= 1
if n > 0:
l.append('0')
n -= 1
print( "".join( l ) )

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
n,k=map(int,input().split())
a=(n-k)//2
for i in range(n):
if((i+1)%(a+1)==0):
print("1",end='')
else:
print("0",end='')

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
#saved
n, k = map(int, input().split())
if n == k:
print('1' * n)
elif k == 1:
print('0' + '1' * (n - 1))
else:
x = (n - k) // 2
a = '0' * x + '1'
print(a * (n // (x + 1)) + '0' * (n % (x + 1)))

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
n, k = list(map(int,input().split()))
chuj_twojej_starej = (n - k) // 2 + 1
i = 1
while True:
if i % chuj_twojej_starej == 0:
print(0, end = "")
else:
print(1, end = "")
if i == n:
break
i += 1

Provide tags and a correct Python 3 solution for this coding contest problem.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Correct Solution:
```
from collections import *
from math import *
n,k = map(int,input().split())
x = (n-k)//2+1
for i in range(1,n+1):
if(i%x) == 0:
print(1,end="")
else:
print(0,end="")
print()

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
import os
import sys
def log(*args, **kwargs):
if os.environ.get('CODEFR'):
print(*args, **kwargs)
n, k = tuple(map(int, input().split()))
s = '0'*((n-k)//2) + '1'
for i in range(n):
print(s[i % len(s)], end='')
print()
```
Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
n,k=map(int,input().strip().split())
d=(n-k)//2+1
x=['1' if (i+1)%d==0 else '0' for i in range(n)]
print(''.join(x))
```
Yes

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
n,k=map(int,input().split())
s="0"
for i in range(1,k):
if(s[i-1]=="0"):
s=s+"1"
else:
s=s+"0"
a="1"*(n-k)
s=a+s
s=s+"1"*(n-len(s))
print(s)
```
No

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
n, k = map(int, input().split())
if n == k:
print('1' * n)
elif n == k + 2:
print('01' * (n // 2) + '0' * (n % 2))
elif n >= 2 * k:
print('0' * k + '10' * ((n - k) // 2))
else:
x = (n - k) // 2
a = '0' * x
c = '0' * x
r = '1' + '0' * x
z = '1'
if (k - 1) % (x + 1) == 0:
z = ''
b = r * ((k - 1) // (x + 1)) + z + '0' * (max(0, (k - 1) % (x + 1)))
print(a+b+'1'+c)
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.

Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
n, k = map(int, input().split())
if n == k:
print('1' * n)
elif n >= 2 * k:
print('0' * k + '10' * ((n - k) // 2))
else:
x = (n - k) // 2
a = '0' * x + '1'
print(a * (n // (x + 1)) + '0' * (n % (x + 1)))
```

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Let s be some string consisting of symbols "0" or "1". Let's call a string t a substring of string s, if there exists such number 1 ≤ l ≤ |s| - |t| + 1 that t = s_l s_{l+1} … s_{l + |t| - 1}. Let's call a substring t of string s unique, if there exist only one such l.
For example, let s = "1010111". A string t = "010" is an unique substring of s, because l = 2 is the only one suitable number. But, for example t = "10" isn't a unique substring of s, because l = 1 and l = 3 are suitable. And for example t ="00" at all isn't a substring of s, because there is no suitable l.
Today Vasya solved the following problem at the informatics lesson: given a string consisting of symbols "0" and "1", the task is to find the length of its minimal unique substring. He has written a solution to this problem and wants to test it. He is asking you to help him.
You are given 2 positive integers n and k, such that (n mod 2) = (k mod 2), where (x mod 2) is operation of taking remainder of x by dividing on 2. Find any string s consisting of n symbols "0" or "1", such that the length of its minimal unique substring is equal to k.
Input
The first line contains two integers n and k, separated by spaces (1 ≤ k ≤ n ≤ 100 000, (k mod 2) = (n mod 2)).
Output
Print a string s of length n, consisting of symbols "0" and "1". Minimal length of the unique substring of s should be equal to k. You can find any suitable string. It is guaranteed, that there exists at least one such string.
Examples
Input
4 4
Output
1111
Input
5 3
Output
01010
Input
7 3
Output
1011011
Note
In the first test, it's easy to see, that the only unique substring of string s = "1111" is all string s, which has length 4.
In the second test a string s = "01010" has minimal unique substring t ="101", which has length 3.
In the third test a string s = "1011011" has minimal unique substring t ="110", which has length 3.
Submitted Solution:
```
n, k = map(int, input().split())
if n == k:
print('1' * n)
elif n == k + 2:
print('01' * (n // 2) + '0' * (n % 2))
else:
z = '0' * ((n - k) // 2)
print(z + '10' * (k // 2) + '1' * (k % 2) + z)
```
No

Provide tags and a correct Python 3 solution for this coding contest problem.
While Mahmoud and Ehab were practicing for IOI, they found a problem which name was Longest common subsequence. They solved it, and then Ehab challenged Mahmoud with another problem.
Given two strings a and b, find the length of their longest uncommon subsequence, which is the longest string that is a subsequence of one of them and not a subsequence of the other.
A subsequence of some string is a sequence of characters that appears in the same order in the string, The appearances don't have to be consecutive, for example, strings "ac", "bc", "abc" and "a" are subsequences of string "abc" while strings "abbc" and "acb" are not. The empty string is a subsequence of any string. Any string is a subsequence of itself.
Input
The first line contains string a, and the second line — string b. Both of these strings are non-empty and consist of lowercase letters of English alphabet. The length of each string is not bigger than 105 characters.
Output
If there's no uncommon subsequence, print "-1". Otherwise print the length of the longest uncommon subsequence of a and b.
Examples
Input
abcd
defgh
Output
5
Input
a
a
Output
-1
Note
In the first example: you can choose "defgh" from string b as it is the longest subsequence of string b that doesn't appear as a subsequence of string a.
Tags: constructive algorithms, strings
Correct Solution:
```
strng1, strng2 = input(), input()
if strng1 == strng2: print(-1)
elif len(strng1) > len(strng2): print(len(strng1))
else: print(len(strng2))
```

Provide tags and a correct Python 3 solution for this coding contest problem.
While Mahmoud and Ehab were practicing for IOI, they found a problem which name was Longest common subsequence. They solved it, and then Ehab challenged Mahmoud with another problem.
Given two strings a and b, find the length of their longest uncommon subsequence, which is the longest string that is a subsequence of one of them and not a subsequence of the other.
A subsequence of some string is a sequence of characters that appears in the same order in the string, The appearances don't have to be consecutive, for example, strings "ac", "bc", "abc" and "a" are subsequences of string "abc" while strings "abbc" and "acb" are not. The empty string is a subsequence of any string. Any string is a subsequence of itself.
Input
The first line contains string a, and the second line — string b. Both of these strings are non-empty and consist of lowercase letters of English alphabet. The length of each string is not bigger than 105 characters.
Output
If there's no uncommon subsequence, print "-1". Otherwise print the length of the longest uncommon subsequence of a and b.
Examples
Input
abcd
defgh
Output
5
Input
a
a
Output
-1
Note
In the first example: you can choose "defgh" from string b as it is the longest subsequence of string b that doesn't appear as a subsequence of string a.
Tags: constructive algorithms, strings
Correct Solution:
```
first = input()
second = input()
m = ''
counter = 0
def compute(a, b):
m = a[:]
counter = len(m)
if a == b:
return -1
for i in range(0, len(m)):
if m not in b:
return counter
else:
counter-=1
m = m[i:]
return counter
print(max(compute(first, second), compute(second, first)))
```

Provide tags and a correct Python 3 solution for this coding contest problem.
While Mahmoud and Ehab were practicing for IOI, they found a problem which name was Longest common subsequence. They solved it, and then Ehab challenged Mahmoud with another problem.
Given two strings a and b, find the length of their longest uncommon subsequence, which is the longest string that is a subsequence of one of them and not a subsequence of the other.
A subsequence of some string is a sequence of characters that appears in the same order in the string, The appearances don't have to be consecutive, for example, strings "ac", "bc", "abc" and "a" are subsequences of string "abc" while strings "abbc" and "acb" are not. The empty string is a subsequence of any string. Any string is a subsequence of itself.
Input
The first line contains string a, and the second line — string b. Both of these strings are non-empty and consist of lowercase letters of English alphabet. The length of each string is not bigger than 105 characters.
Output
If there's no uncommon subsequence, print "-1". Otherwise print the length of the longest uncommon subsequence of a and b.
Examples
Input
abcd
defgh
Output
5
Input
a
a
Output
-1
Note
In the first example: you can choose "defgh" from string b as it is the longest subsequence of string b that doesn't appear as a subsequence of string a.
Tags: constructive algorithms, strings
Correct Solution:
```
a=str(input())
b=str(input())
c=list(b)
d=list(a)
if a==b:
print(-1)
elif len(c)==0 or len(d)==0:
print(-1)
else:
print(max(len(c),len(d)))
```

Provide tags and a correct Python 3 solution for this coding contest problem.
While Mahmoud and Ehab were practicing for IOI, they found a problem which name was Longest common subsequence. They solved it, and then Ehab challenged Mahmoud with another problem.
Given two strings a and b, find the length of their longest uncommon subsequence, which is the longest string that is a subsequence of one of them and not a subsequence of the other.
A subsequence of some string is a sequence of characters that appears in the same order in the string, The appearances don't have to be consecutive, for example, strings "ac", "bc", "abc" and "a" are subsequences of string "abc" while strings "abbc" and "acb" are not. The empty string is a subsequence of any string. Any string is a subsequence of itself.
Input
The first line contains string a, and the second line — string b. Both of these strings are non-empty and consist of lowercase letters of English alphabet. The length of each string is not bigger than 105 characters.
Output
If there's no uncommon subsequence, print "-1". Otherwise print the length of the longest uncommon subsequence of a and b.
Examples
Input
abcd
defgh
Output
5
Input
a
a
Output
-1
Note
In the first example: you can choose "defgh" from string b as it is the longest subsequence of string b that doesn't appear as a subsequence of string a.
Tags: constructive algorithms, strings
Correct Solution:
```
a = input()
b = input()
if a == b:
otv = -1
elif len(a) > len(b):
otv = len(a)
else:
otv = len(b)
print(otv)
```

Provide tags and a correct Python 3 solution for this coding contest problem.
While Mahmoud and Ehab were practicing for IOI, they found a problem which name was Longest common subsequence. They solved it, and then Ehab challenged Mahmoud with another problem.
Given two strings a and b, find the length of their longest uncommon subsequence, which is the longest string that is a subsequence of one of them and not a subsequence of the other.
A subsequence of some string is a sequence of characters that appears in the same order in the string, The appearances don't have to be consecutive, for example, strings "ac", "bc", "abc" and "a" are subsequences of string "abc" while strings "abbc" and "acb" are not. The empty string is a subsequence of any string. Any string is a subsequence of itself.
Input
The first line contains string a, and the second line — string b. Both of these strings are non-empty and consist of lowercase letters of English alphabet. The length of each string is not bigger than 105 characters.
Output
If there's no uncommon subsequence, print "-1". Otherwise print the length of the longest uncommon subsequence of a and b.
Examples
Input
abcd
defgh
Output
5
Input
a
a
Output
-1
Note
In the first example: you can choose "defgh" from string b as it is the longest subsequence of string b that doesn't appear as a subsequence of string a.
Tags: constructive algorithms, strings
Correct Solution:
```
s = input()
w = input()
print('-1' if s == w else max(len(s), len(w)))
```
