Given an alphanumeric string made up of digits and lower case Latin characters only, find the sum of all the digit characters in the string.

-----Input-----
- The first line of the input contains an integer T denoting the number of test cases. Then T test cases follow.
- Each test case is described with a single line containing a string S, the alphanumeric string.

-----Output-----
- For each test case, output a single line containing the sum of all the digit characters in that string.

-----Constraints-----
- 1 ≤ T ≤ 1000
- 1 ≤ |S| ≤ 1000, where |S| is the length of the string S.

-----Example-----
Input:
1
ab1231da

Output:
7

-----Explanation-----
The digits in this string are 1, 2, 3 and 1. Hence, the sum of all of them is 7.

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.

A string with length $L$ is called rich if $L \ge 3$ and there is a character which occurs in this string strictly more than $L/2$ times.
You are given a string $S$ and you should answer $Q$ queries on this string. In each query, you are given a substring $S_L, S_{L+1}, \ldots, S_R$. Consider all substrings of this substring. You have to determine whether at least one of them is rich.

-----Input-----
- The first line of the input contains a single integer $T$ denoting the number of test cases. The description of $T$ test cases follows.
- The first line of each test case contains two space-separated integers $N$ and $Q$.
- The second line contains a single string $S$ with length $N$.
- Each of the next $Q$ lines contains two space-separated integers $L$ and $R$ describing a query.

-----Output-----
For each query, print a single line containing the string "YES" if the given substring contains a rich substring or "NO" if it does not contain any rich substring.

-----Constraints-----
- $1 \le T \le 10$
- $1 \le N, Q \le 10^5$
- $1 \le L \le R \le N$
- $S$ contains only lowercase English letters

-----Example Input-----
1
10 2
helloworld
1 3
1 10

-----Example Output-----
NO
YES

=====Problem Statement=====
Integers in Python can be as big as the bytes in your machine's memory. There is no limit in size as there is: 2^31 - 1 (c++ int) or 2^63 - 1 (C++ long long int).
As we know, a^b the result of grows really fast with increasing b.
Let's do some calculations on very large integers.
Task
Read four numbers, a, b, c, and d, and print the result of a^b + c^d.

=====Input Format=====
Integers a, b, c, and d are given on four separate lines, respectively.

=====Constraints=====
1≤a≤1000
1≤b≤1000
1≤c≤1000
1≤d≤1000

=====Output Format=====
Print the result of a^b + c^d on one line.

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.

Given a string s. Can you make it a palindrome by deleting exactly one character? Note that size of the string after deletion would be one less than it was before. 

-----Input-----
First line of the input contains a single integer T denoting number of test cases.
For each test case, you are given a single line containing string  s. 

-----Output-----
For each test case, print YES or NO depending on the answer of the problem. 

-----Constraints-----
Subtask 1, 35 points 
-  1 ≤ T ≤ 100
- 2 ≤  size of string s ≤ 1000
-  String s contains lowercase English alphabets (ie. from 'a' to 'z').

Subtask 2, 65 points 
- 2 ≤  size of string s ≤ 10^5
-  Sum of size of string s over all the input test cases won't exceed 10^6
-  String s contains lowercase English alphabets (ie. from 'a' to 'z').

-----Example-----
Input:
4
aaa
abc
abdbca
abba

Output:
YES
NO
YES
YES

-----Explanation-----
Example case 1. Delete any one 'a', resulting string is "aa" which is a palindrome.
Example case 2. It is not possible to delete exactly one character and having a palindrome.
Example case 3. Delete 'c', resulting string is "abdba" which is a palindrome. 
Example case 4. Delete 'b', resulting string is "aba" which is a palindrome.

Rachel has some candies and she decided to distribute them among $N$ kids. The ith kid receives $A_i$ candies. The kids are happy iff the difference between the highest and lowest number of candies received is less than $X$.
Find out if the children are happy or not.

-----Input:-----
- First line will contain $T$, number of testcases. Then the testcases follow. 
- The first line contains $N$ and $X$. 
- The second line contains $N$ integers $A_1,A_2,...,A_N$. 

-----Output:-----
For each test case print either "YES"(without quotes) if the kids are happy else "NO"(without quotes)

-----Constraints-----
- $1 \leq T \leq 100$
- $1 \leq N, X \leq 10^5$
- $1 \leq A_i \leq 10^5$

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

5 6

3 5 6 8 1

3 10

5 2 9

-----Sample Output:-----
NO

YES

-----EXPLANATION:-----
- Example 1: Difference between maximum and minimum candies received is 8-1=7. 7 is greater than 6, therefore, the kids are not happy.

Complete the function that takes one argument, a list of words, and returns the length of the longest word in the list.

For example: 

```python
['simple', 'is', 'better', 'than', 'complex'] ==> 7
```
