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::io;

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

fn read_ints() -> Vec<i32>{
    let s = read_line();
    let split:Vec<&str> = s.trim().split(" ").collect();
    split.iter().map(|&x| x.to_string().parse().unwrap()).collect()
}

fn main(){
    //let array = read_ints();
    //let x = array[0];
    //let y = array[1];
    
    let line = read_line();
    let x = line.chars().nth(0).unwrap();
    let y = line.chars().nth(2).unwrap();

    let x = x as i32;
    let y = y as i32;

    match (x-y) {
        n if n < 0 => println!("<"),
        n if n > 0 => println!(">"),
        _ => println!("=")
    }
}
