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: Wrong Answer)

function Main(input){
    input = input.split(" ");

    input[0] = parseInt(input[0], 10);
    input[1] = parseInt(input[1], 10);
    input[2] = parseInt(input[2], 10);
    input[3] = parseInt(input[3], 10);

    if(input[2] >= input[1]){
        console.log(0);
    }else if(input[3] <= input[0]){
        console.log(0);
    }else{
        if(input[0] < input[2]){
            var start = input[2]
        }else{
            var start = input[0]
        }

        if(input[1] < input[3]){
            var end = input[1]
        }else{
            var end = input[3]
        }

        console.log('%d', end - start);
    }
}
