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 =.

=

15 = 15.

Solution in Perl (v5.18.2) (judge verdict: Accepted)

use strict;
use warnings;

my %n = (
    A => 10,
    B => 11,
    C => 12,
    D => 13,
    E => 14,
    F => 15,
);

my $s = <STDIN>;
chomp $s;
my ($a, $b) = split / /, $s;

if ($n{$a} < $n{$b}) {
    print '<';
} elsif ($n{$a} > $n{$b}) {
    print '>';
} else {
    print '=';
