a string S convert it to a palindrome by doing chara, C/C++ Programming

Assignment Help:
A palindrome is a string that reads the same from both the ends. Given a string S convert it to a palindrome by doing character replacement. Your task is to convert S to palindromes with minimum number of character replacements.

Input Format:

First line starts with T, which is the number of test cases. Each test case contains a string (S).

Output Format:

For each test case print the minimum number of character replacements needed to convert the given string to palindrome.

Constraints:
1<=T<=100

1<=|S|<=60, S will contains only lower case alphabets (''a''-''z'')
