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 Ruby (2.3.3) (judge verdict: Accepted)

lines = $stdin.read
array = lines.split("\n")
 
X,Y = array[0].split(" ").map(&:to_s)
 
hex = { 'A' => 10,
        'B' => 11,
        'C' => 12,
        'D' => 13,
        'E' => 14,
        'F' => 15}
 
if hex[X] == hex[Y]
  puts "="
elsif hex[X] > hex[Y]
  puts ">"
else
  puts "<"
end
