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
$hextable = array(
    "A" => 10,
    "B" => 11,
    "c" => 12,
    "D" => 13,
    "E" => 14,
    "F" => 15 
);

fscanf(STDIN,"%s %s",$x,$y);
if($hextable[$x] < $hextable[$y]) echo "<";
elseif($x == $y) echo "=";
else echo ">";


?>
