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 Rust (1.15.1) (judge verdict: Accepted)

use std::error::Error;
use std::io;

fn main() {
    if let Err(e) = run() {
        println!("{}", e);
    }
}

fn run() -> Result<(), Box<Error>> {
    let mut n = String::new();
    io::stdin().read_line(&mut n)?;
    let n = n.trim().as_bytes();
    if n[0] == n[2] {
        println!("Yes");
    } else {
        println!("No");
    }
    Ok(())
}
