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 main(void){
	
	char c;
	
	int number[4];
	
	int i,k;
	
	for(i=1;i<=3;i++){
		
		c = getchar ();
		
		k = c - 48;
		
		number[i] = k;
		
	}
	
	if(number[1] == number[3]){
		
		printf ("Yes\n");
		
	}else{
		
		printf ("No\n");
		
	}
	
	return 0;
