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)


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


fn main() {
  let chars: Vec<_>
    = read_line().split(" ").map(|n| n.chars().nth(0).unwrap()).collect();
  let (x, y)
    = (chars[0].to_digit(16).unwrap(), chars[1].to_digit(16).unwrap());
  let ans = if x < y {
    '<'
  } else if x > y {
    '>'
  } else {
    '='
  };
  println!("{}", ans);
}
