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<bits/stdc++.h>
using namespace std;
using ll = long long;

int main(){

    string s;
    cin >> s;
    string t = s;
    reverse(s.begin(), s.end());
    if(s == t) cout << "Yes" << endl;
    else cout << "No" << endl;
    
    
    return 0;
