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 main(){
	let mut s = String::new();
	std::io::stdin().read_line(&mut s).unwrap();
	let n: i32 = s.trim().parse().unwrap();
	let mut m = n;
	let mut p = 0;
	while m > 0 {
		p += m % 10;
		p *= 10;
		m /= 10;
	}
	if n == (p / 10) {
		println!("Yes");
	} else {
		println!("No");
	}
