Problem Statement

You are given a three-digit positive integer N.

Determine whether N is a palindromic number.

Here, a palindromic number is an integer that reads the same backward as forward in decimal notation.

Constraints

100≤N≤999

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N is a palindromic number, print Yes; otherwise, print No.

Sample Input 1

575

Sample Output 1

Yes

N=575 is also 575 when read backward, so it is a palindromic number. You should print Yes.

Sample Input 2

123

Sample Output 2

No

N=123 becomes 321 when read backward, so it is not a palindromic number. You should print No.

Sample Input 3

812

Sample Output 3

No

Solution in Java8 (OpenJDK 1.8.0) (judge verdict: Accepted)

import java.util.*;

public class Main {
    private static final String ex = "575";

    public static void main(String[] args) {
        System.out.println(solve(new Scanner(System.in)));
//        System.out.println(solve(new Scanner(ex)));
    }

    private static String solve(Scanner scanner) {
        String s = scanner.nextLine();
        return s.charAt(0) == s.charAt(2) ? "Yes" : "No";
    }
}
