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)

fn read_input() -> String {
    let mut s = String::new();
    std::io::stdin().read_line(&mut s).expect("");
    s
}

fn main() {
    let s = read_input();
    let mut s = s.chars();
    let a = s.nth(0);
    let b = s.nth(1);
    if a == b {
        println!("Yes");
    } else {
        println!("No");
    }
}
