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

Sample Output 3

=

15 = 15.

Solution in Scala (2.11.7) (judge verdict: Accepted)

import java.util.Scanner

object Main extends App {
  val sc = new Scanner(System.in)

  val x = sc.next
  val y = sc.next

  val alphabets = "ABCDEF"

  val res =
    if(alphabets.indexOf(x) > alphabets.indexOf(y)) ">"
    else if (alphabets.indexOf(x) < alphabets.indexOf(y)) "<"
    else "="

  println(res)

}
