The first line contains 'T' denoting the number of test cases. Then follows description of test cases.
Each case begins with a single integer N denoting the length of string. The next line contains the string s.

Output:
Print "Yes" if it is a palindrome else "No". (Without the double quotes)

Constraints:
1<=T<=30
1<=N<=100

Example:
Input:
1
4
abba

Output:
Yes

CODE:

import java.util.*;

import java.lang.*;

import java.io.*;

class GFG {

public static void main (String[] args) {

Scanner sc = new Scanner (System.in);

int m =sc.nextInt();

for(int mi=0;mi<m;mi++){

   int n=sc.nextInt();

   String s1 =sc.next();

  // System.out.print(s1+" ");

   char [] t1= s1.toCharArray();

   int count=0;

   for(int i=n-1;i>=0;i--){

       if(t1[i]==t1[n-i-1]){

           count++;

       }

   }

   if(count>=n/2){

       System.out.println("Yes");

   }

   else{System.out.println("No");}
