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 JavaScript (node.js v5.12) (judge verdict: Accepted)

function Main(input){
  var inp = input.split(' ');
  var X = inp[0];
  // 'A'の文字コードは65。'A'を10とするために65-10=55を引く
  var Xc = inp[0].charCodeAt() - 55;

  var Y = inp[1];
  var Yc = inp[1].charCodeAt() - 55;

  if(Xc < Yc){
    console.log('<');
  } else if(Xc > Yc){
    console.log('>');
  } else {
    console.log('=');
  }
}

Main(require('fs').readFileSync('/dev/stdin', 'utf8'));
