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,a[3];
  a[0] = n/100;
  a[1] = n/10;
  a[2] =n - (a[0]*100+a[1]*10);
  if(n%111 ==0){
    cout<<"Yes"<<endl;
    return 0;
  }else if( a[0] == a[2])  {
    cout<<"Yes"<<endl;
    return 0;
  } else{
    cout<<"No"<<endl;
    return 0;
  }
