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++14 (Clang 3.8.0) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <string.h>

int main(){
	char angka[150];
	int cek = 0;
	scanf("%s", angka);
	int x = strlen(angka) - 1;
	for(int i = 0 ; i <= x ; i++, x--){
		if(angka[i] != angka[x]){
			cek = 1;
			break;
		}
	}
	if(cek == 1) printf("NO\n");
	else printf("YES\n");
	
	return 0;
