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 PHP (5.6.30) (judge verdict: Accepted)

<?php
	fscanf(STDIN, "%s %s", $X, $Y);

	$num1 = 0;
	$num2 = 0;

	switch ($X){
		case "A":
			$num1 = 10;
			break;

		case "B":
			$num1 = 11;
			break;

		case "C":
			$num1 = 12;
			break;

		case "D":
			$num1 = 13;
			break;

		case "E":
			$num1 = 14;
			break;


		case "F":
			$num1 = 15;
			break;

	}

	switch ($Y){
		case "A":
			$num2 = 10;
			break;

		case "B":
			$num2 = 11;
			break;

		case "C":
			$num2 = 12;
			break;

		case "D":
			$num2 = 13;
			break;

		case "E":
			$num2 = 14;
			break;


		case "F":
			$num2 = 15;
			break;

	}

	// 出力
	if ($num1 > $num2){
		echo ">\n";
	} elseif ($num1 < $num2) {
		echo "<\n";
	} elseif ($num1 == $num2) {
		echo "=\n";
	}
