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 JavaScript (node.js v5.12) (judge verdict: Accepted)

/**
 * @param {String} input
 */
function Main(input){
	var inputs = input.split("\n")[0].split('');
	return (inputs[0] == inputs[2]) ? 'Yes' : 'No';
}
console.log(Main(require("fs").readFileSync("/dev/stdin", "utf8")));
