Problem Statement

In programming, hexadecimal notation is often used.

In hexadecimal notation, besides the ten digits 0, 1, ..., 9, the six letters A, B, C, D, E and F are used to represent the values 10, 11, 12, 13, 14 and 15, respectively.

In this problem, you are given two letters X and Y. Each X and Y is A, B, C, D, E or F.

When X and Y are seen as hexadecimal numbers, which is larger?

Constraints

Each X and Y is A, B, C, D, E or F.

Input

Input is given from Standard Input in the following format:

X Y

Output

If X is smaller, print <; if Y is smaller, print >; if they are equal, print =.

Sample Input 1

A B

Sample Output 1

<

10 < 11.

Sample Input 2

E C

Sample Output 2

>

14 > 12.

Sample Input 3

F F

Sample Output 3

=

15 = 15.

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::str::FromStr;
use std::io::stdin;

fn read<T: FromStr>() -> T{
    let mut s = String::new();
    stdin().read_line(&mut s).ok();
    s.trim().parse().ok().unwrap()
}

fn read_vec<T: FromStr>() -> Vec<T> {
    read::<String>().split_whitespace()
                    .map(|e| e.parse().ok().unwrap())
                    .collect()
}

fn main() {
    let xy = read_vec::<String>();
    let x = &xy[0];
    let y = &xy[1];
    if x < y {
        println!("<");
    } else if x > y {
        println!(">");
    } else {
        println!("=");
    }
}
