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

    String s = sc.next();
    String hundreds = s.substring(0, 1);

    String ones = s.substring(2, 3);
    
    String reverseOfS = hundreds + tens + ones;
    
    if (s.equals(reverseOfS)) {
      System.out.println("Yes");
    } else {
      System.out.println("No");
