A palindrome is a string that is the same whether it is read from left to right or from right to left. Chota Bheem likes palindromes a lot. As a birthday gift he received two strings A and B. Now he is curious if there is a way to insert string B into string A so that the resulting string is a palindrome. You agreed to help him and even tell how many different variants of such insertions exist. Two variants are considered different if string B is inserted in different places. Print the number of possible insertion variants.

Input:-
1st line input the number of testcases and next two lines of each test case contains A and B. 

Output:- 
Print the number of variants.

SAMPLE INPUT
1
aba
b

SAMPLE OUTPUT
2

Explanation

You can insert B in 4 different places:
Before the first letter of A. The result is "baba" and it is not a
   palindrome.
After the first letter 'a'. The result is "abba" and it is a
   palindrome.
After the letter 'b'.The result is "abba" and it is also a
   palindrome.
After the second letter 'a'. The result is "abab" and it is not a
   palindrome.

So, the answer for this testcase is 2.
