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,t,sum;
    while(cin>>n)
    {
    	sum=0;
    	t=n;
    	while(n)
    	{
	    	sum=sum*10+n%10; 
        	n/=10;
	    }
	    if(t==sum) 
        cout<<"Yes"<<endl;
    	else
        cout<<"No"<<endl;
    }
