        String A=sc.next();

        /* Enter your code here. Print output to STDOUT. */

        String R = new StringBuilder(A).reverse().toString();

        if(A.equals(R)) System.out.println("Yes");

        else System.out.println("No");

    }

}

Program 2:

import java.io.*;

import java.util.*;

public class Solution {

   public static void main(String[] args) {

        Scanner sc=new Scanner(System.in);

        String A=sc.next();

        /* Enter your code here. Print output to STDOUT. */

        int count = 0;

        for(int i=0; i<A.length()/2;i++)

            if( A.charAt(i) == A.charAt(A.length()-i-1)) count++;

        System.out.println( (count == A.length()/2) ? "Yes" : "No") ;

    }
