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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>
int clc(int n){
	int rev_n=0;
	while(n!=0){
		rev_n*=10;
		rev_n+=n%10;
		n/=10;
	}
	return rev_n;
}
int main()
{
	int n, rev_n;
	scanf("%d", &n);
	rev_n=clc(n);
	if(n==rev_n)printf("Yes\n");
	else printf("No");
	return 0;
