akhauriyash/Code-Regression huggingface dataset:
You are given a string s of length n.
Does a tree with n vertices that satisfies the following conditions exist?
 - The vertices are numbered 1,2,..., n.
 - The edges are numbered 1,2,..., n-1, and Edge i connects Vertex u_i and v_i.
 - If the i-th character in s is 1, we can have a connected component of size i by removing one edge from the tree.
 - If the i-th character in s is 0, we cannot have a connected component of size i by removing any one edge from the tree.
If such a tree exists, construct one such tree.

-----Constraints-----
 - 2 \leq n \leq 10^5
 - s is a string of length n consisting of 0 and 1.

-----Input-----
Input is given from Standard Input in the following format:
s

-----Output-----
If a tree with n vertices that satisfies the conditions does not exist, print -1.
If a tree with n vertices that satisfies the conditions exist, print n-1 lines.
The i-th line should contain u_i and v_i with a space in between.
If there are multiple trees that satisfy the conditions, any such tree will be accepted.

-----Sample Input-----
1111

-----Sample Output-----
-1

It is impossible to have a connected component of size n after removing one edge from a tree with n vertices.

Hooray! Polycarp turned $n$ years old! The Technocup Team sincerely congratulates Polycarp!

Polycarp celebrated all of his $n$ birthdays: from the $1$-th to the $n$-th. At the moment, he is wondering: how many times he turned beautiful number of years?

According to Polycarp, a positive integer is beautiful if it consists of only one digit repeated one or more times. For example, the following numbers are beautiful: $1$, $77$, $777$, $44$ and $999999$. The following numbers are not beautiful: $12$, $11110$, $6969$ and $987654321$.

Of course, Polycarpus uses the decimal numeral system (i.e. radix is 10).

Help Polycarpus to find the number of numbers from $1$ to $n$ (inclusive) that are beautiful.


-----Input-----

The first line contains an integer $t$ ($1 \le t \le 10^4$) — the number of test cases in the input. Then $t$ test cases follow.

Each test case consists of one line, which contains a positive integer $n$ ($1 \le n \le 10^9$) — how many years Polycarp has turned.


-----Output-----

Print $t$ integers — the answers to the given test cases in the order they are written in the test. Each answer is an integer: the number of beautiful years between $1$ and $n$, inclusive.


-----Example-----
Input
6
18
1
9
100500
33
1000000000

Output
10
1
9
45
12
81



-----Note-----

In the first test case of the example beautiful years are $1$, $2$, $3$, $4$, $5$, $6$, $7$, $8$, $9$ and $11$.

Andrii is good in Math, but not in Programming. He is asking you to solve following problem: Given an integer number N and two sets of integer A and B. Let set A contain all numbers from 1 to N and set B contain all numbers from N + 1 to 2N. Multiset C contains all sums a + b such that a belongs to A and b belongs to B. Note that multiset may contain several elements with the same values. For example, if N equals to three, then A = {1, 2, 3}, B = {4, 5, 6} and C = {5, 6, 6, 7, 7, 7, 8, 8, 9}. Andrii has M queries about multiset C. Every query is defined by a single integer q. Andrii wants to know the number of times q is contained in C. For example, number 6 is contained two times, 1 is not contained in C at all. 

Please, help Andrii to answer all the queries.

-----Input-----

The first line of the input contains two integers N and M. Each of the next M line contains one integer q, the query asked by Andrii.

-----Output-----
Output the answer for each query in separate lines as in example.

-----Constraints-----
- 1 ≤ N ≤ 109
- 1 ≤ M ≤ 105
- 1 ≤ q ≤ 3N

-----Example-----
Input:

Dhote and Shweta went on a tour by plane for the first time.Dhote was surprised by the conveyor belt  at the airport.As Shweta was getting bored Dhote had an idea of playing a game with her.He asked Shweta to count the number of bags whose individual weight is greater than or equal to the half of the total number of bags on the conveyor belt.Shweta got stuck in the puzzle! Help Shweta. 

-----Input:-----
- First line will contain T$T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, one  integers N$N$.
- next line conatins N$N$ integers that represents weight of bag 

-----Output:-----
For each testcase, print required answer in new line .

-----Constraints-----
- 1≤T≤1000$1 \leq T \leq 1000$

Chef likes strings a lot but he likes palindromic strings more. Today, Chef has two strings A and B, each consisting of lower case alphabets.

Chef is eager to know whether it is possible to choose some non empty strings s1 and s2 where s1 is a substring of A, s2 is a substring of B such that s1 + s2 is a palindromic string. Here '+' denotes the concatenation between the strings.
Note:
A string is a palindromic string if it can be read same both forward as well as backward. To know more about palindromes click here.

-----Input-----
- First line of input contains a single integer T denoting the number of test cases.
- For each test case:
	
- First line contains the string A
- Second line contains the string B.

-----Output-----
For each test case, Print "Yes" (without quotes) if it possible to choose such strings s1 & s2. Print "No" (without quotes) otherwise.


-----Constraints-----
- 1 ≤ T ≤ 10 
- 1 ≤ |A|, |B| ≤ 1000 

-----Subtasks-----
-  Subtask 1: 1 ≤ |A|, |B| ≤ 10 : ( 40 pts )
-  Subtask 2: 1 ≤ |A|, |B| ≤ 1000 : ( 60 pts )

-----Example-----Input
3
abc
abc
a
b
abba
baab

Output
Yes
No
Yes

-----Explanation-----
- Test 1: One possible way of choosing s1 & s2 is s1 = "ab", s2 = "a" such that s1 + s2 i.e "aba" is a palindrome.
- Test 2: There is no possible way to choose s1 & s2 such that s1 + s2 is a palindrome.
- Test 3: You can figure it out yourself.

Meliodas and Ban are fighting over chocolates. Meliodas has $X$ chocolates, while Ban has $Y$. Whoever has lesser number of chocolates eats as many chocolates as he has from the other's collection. This eatfest war continues till either they have the same number of chocolates, or atleast one of them is left with no chocolates.

Can you help Elizabeth predict the total no of chocolates they'll be left with at the end of their war?

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input, which contains two integers $X, Y$, the no of chocolates Meliodas and Ban have, respectively. 

-----Output:-----
For each testcase, output in a single line the no of chocolates that remain after Ban and Meliodas stop fighting.

-----Constraints-----
- $1 \leq T \leq 100000$
- $0 \leq X,Y \leq 10^9$

-----Sample Input:-----
3

5 3

10 10

4 8  

-----Sample Output:-----
2

20

8  

-----EXPLANATION:-----
Denoting Meliodas as $M$, Ban as $B$.
Testcase 1:
$M$=5, $B$=3

Ban eates 3 chocolates of Meliodas.
$M$=2, $B$=3

Meliodas eats 2 chocolates of Ban.
$M$=2, $B$=1

Ban eates 1 chocolate of Meliodas.
$M$=1, $B$=1

Since they have the same no of candies, they stop quarreling.

Total candies left: 2  
Testcase 2:
$M$=10, $B$=10

Since both of them had the same candies to begin with, there was no point in fighting.

Total candies left: 20  
Testcase 3:
$M$=4, $B$=8

Meliodas eats 4 chocolates of Ban.
$M$=4, $B$=4

Since they have the same no of candies, they stop quarreling.

Total candies left: 8

You are given a string s of length 8 consisting solely of '0's and '1's. Assume that the characters of the string are written in a circular fashion. You need to find the number of 0-1 or 1-0 transitions that one has to make while making a single traversal over the string. ie. start from any character and go circularly until you get back to the same character, and find the number of transitions that you made. The string is said to be said to be uniform if there are at most two such transitions. Otherwise, it is called non-uniform.
Given the string s, tell whether the string is uniform or not.

-----Input-----
The first line of the input contains an integer T denoting the number of test cases. The description of T test cases follows.
The only line of input contains the string s.

-----Output-----
For each test case, output "uniform" if the given string is uniform and "non-uniform" otherwise.

-----Constraints-----
- 1 ≤ T ≤ 256
- Length of s is 8

-----Example-----
Input
4
00000000
10101010
10000001
10010011

Output
uniform
non-uniform
uniform
non-uniform

-----Explanation-----
The number of transitions are 0, 8, 2 and 4 for the respective cases. So, the first and third one are uniform while the second and fourth one are non-uniform.

Kshitij has recently started solving problems on codechef. As he is real problem solving enthusiast, he wants continuous growth in number of problems solved per day.
He started with $a$  problems on first day. 
He solves $d$ problems more than previous day. But after every $k$ days , he increases $d$ by
$inc$ .
Can you guess how many questions he will solve on $nth $ day ?

-----Input:-----
- First line  contains $T$, number of testcases. Then the testcases follow. 
- Each testcase contains of a single line of input,five integers $a, d, k, n, inc$. 

-----Output:-----
For each testcase, output in a single line number of questions solved on $nth$ day.

-----Constraints-----
- $1 \leq T \leq 15$
- $1 \leq a \leq 99$
- $1 \leq d \leq 100$
- $1 \leq n \leq 10000$
- $1 \leq k \leq n$
- $0 \leq inc \leq 99$

-----Sample Input:-----
1
1 4 3 8 2

-----Sample Output:-----
43

-----EXPLANATION:-----
The number of questions solved in first 8 days is :
$1$ $5$ $9$ $15$ $21$ $27$ $35$ $43$ .
On first day he solved 1 problem . Here $d$ is  4 for first 3 days.
Then after 3 days $d$ increases by 2 (that is 6).

Mance Rayder, the King-Beyond-the-Wall, has always wanted to lead the largest army the North has ever seen against the NIght’s Watch. For this humungous feat he has banded the waring tribes, the Giants, Thenns and Wildings, together by going to great extents. But the King is facing with an issue he always saw it coming.
The huge army is divided into smaller divisions and each division can be of the type $G, T$ or $W$ standing for Giants, Thenns and Wildings respectively. Mance doesn’t want two divisions of the same type standing together as he fears it might lead to a mutiny or an unorganised charge or retreat. 
For a given numbers of $G, T$ and $W$, find whether an army can be organised in accordance to the rules set by Mance. Not to forget that Mance has to include all the divisions in his battle formation in order to stand a chance against the Wall’s defences.

-----Input:-----
- First line will contain $N$, the number of test cases.
- Each of the next $N$ lines will contain three integers $G$, $T$ and $W$ - the number of Giant, Thenn and Wildling divisions respectively.

-----Output:-----
For each testcase, output in a single line $Yes$ if a battle formation is possible or $No$ otherwise.

-----Constraints-----
- $1 \leq N \leq 100$
- $1 \leq G,T,W \leq 10^9$

-----Sample Input:-----
1
1 2 1

-----Sample Output:-----
Yes

-----Explanation:-----
The first case can be formed as : $ TGWT $. Hence the answer is $ Yes $.

Correct this code so that it takes one argument, `x`, and returns "`x` is more than zero" if `x` is positive (and nonzero), and otherwise, returns "`x` is equal to or less than zero." In both cases, replace `x` with the actual value of `x`.

As lockdown is going on so no is allowed to go outside , so Chef has come with an innovative idea for food home delivery using drone.  But there is an issue with it , the drone can move forward or backward a fix number of steps $x$ . 
All the houses and chef restaurant are all in a straight line . Homes which need delivery are located at $H[i]$ and chef is located at $y$ coordinate . 
If Drone is at a location $R$, then it can move to $R-x$ or $R+x$ . 
Help chef find maximum value of $x$ to complete all the deliveries as he is busy managing the orders.

-----Input:-----
- First line will contain $n$ and $R$, number of houses that need delivery and the correct coordinate of chef (Drone).
- Second line contains $n$ integers , the coordinate of all homes that need delivery. 

-----Output:-----
- The maximum value of $x$ , so that drone delivers to all houses.

-----Constraints-----
- $1 \leq n \leq 1000$
- $1 \leq R \leq 10^9$
- $1 \leq hi \leq 10^9$
- $1 \leq x  \leq 10^9$

-----Sample Input:-----
3 1
3 5 11

-----Sample Output:-----
2

-----EXPLANATION:-----
Chef's drone is at 1 initially and he needs to visit 3,5,11 , so optimal solution will be (maximum value of x ) equal to 2.
