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 =.

def get_num(num)
  case num
  when 'A'
    10
  when 'B'
    11
  when 'C'
    12
  when 'D'
    13  
  when 'E'
    14
  when 'F'
    15
  end
end
  
x,y=gets.split.map &:to_s
rx=get_num(x)
ry=get_num(y)

if rx < ry
  puts '<'
elsif rx > ry
  puts '>'
elsif rx === ry
  puts '='
