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

using System;
using System.Linq;
class GFG
{
    public static void Main()
    {
        //var input = Console.ReadLine().Split(' ');

        //var x = int.Parse(input[0]);
        //var a = int.Parse(input[1]);
        //var b = int.Parse(input[2]);

        //var n = int.Parse(Console.ReadLine());
        // var ss = str.ToCharArray().OrderBy(x => x).ToArray();
        var s1 = Console.ReadLine();
        // var s2 = Console.ReadLine();

        Pallindrom(s1);
    }

    static void Pallindrom(string n)
    {

        int l = 0;
        int r = n.Length - 1;

        while (l >= r)
        {
            if (n[l] != n[r])
            {
                Console.Write("No");
                return;
            }
            l++;
            r--;
        }
        Console.Write("Yes");
    }
