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()
{
	char a[4];
	int i,c=0,hantei=0;
	scanf("%s",a);

	for(i=0;a[i]!='\0';i++){
		c++;
	}

	for(i=0;i<=c-1;i++){
		if(a[i] != a[c-1-i])
			hantei++;
	}
	
	printf("%s\n",hantei?"No":"Yes");
	return 0;
}
