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::prelude::*;
use std::str::FromStr;

fn main() {
    let stdin = std::io::stdin();
    let mut handle = stdin.lock();
    let mut string = String::new();
    handle.read_to_string(&mut string).unwrap();
    let mut splits = string.split_whitespace();
    let num1: u32 = u32::from_str_radix(splits.next().unwrap().as_ref(), 16).
                                 unwrap();
    let num2: u32 = u32::from_str_radix(splits.next().unwrap().
                                 as_ref(), 16).unwrap();
    if num1 < num2 {
        println!("<");
    } else if num1 == num2 {
        println!("=");
    } else {
        println!(">");
    }
}
