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

#include <iostream>

using namespace std;

int main()
{
    int n,b,c, sum =0 ;
    cin >> n ;
    b=n;
    if(b>=100 && b<=999)
    {
    while (n)
    {
        c=n%10;
        n=n/10;
        sum = sum *10 + c ;
        
        

    }

    if (sum==b)
        cout << "YES";
    else
        cout << "NO";
    }

    return 0;
}
