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 =.

<?php
fscanf(STDIN, "%s %s", $x, $y);
$factors = [];
for ($tmp = 0; $tmp < 6; $tmp++){
    $factors[chr(ord('A')+$tmp)] = $tmp+10;
}
if ($factors[$x] < $factors[$y]){
    print "<\n";
} else if($factors[$x] > $factors[$y]){
    print ">\n";
} else {
    print "=\n";
}
?>
