module Anagram
//Hackerrank problem
//Anagram
// Sid is obsessed with reading short stories. Being a CS student, he is doing some interesting frequency
// analysis with the books. He chooses strings and in such a way that .
// Your task is to help him find the minimum number of characters of the first string he needs to change to
// enable him to make it an anagram of the second string.
// Note: A word x is an anagram of another word y if we can produce y by rearranging the letters of x.
// Input Format
module PalindromeIndex
//Hackertank problem
//Palindrome Index
// Given a string, , of lowercase letters, determine the index of the character whose removal will make a
// palindrome. If is already a palindrome or no such character exists, then print . There will always be a
// valid solution, and any correct answer is acceptable. For example, if "bcbc", we can either remove 'b'
// at index or 'c' at index .
// Input Format
// The first line contains an integer, , denoting the number of test cases.
// Each line of the subsequent lines (where ) describes a test case in the form of a single string,
