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
