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.

using System;
class Program{
    static void Main(){
        // Your code here!
        string[] input = Console.ReadLine().Split(' ');
        string x = input[0];
        string y = input[1];
        int xNum = StringToNumber(x);
        int yNum = StringToNumber(y);
        if(xNum > yNum){
            Console.WriteLine(">");
        }else if(xNum == yNum){
            Console.WriteLine("=");
        }else{
            Console.WriteLine("<");
        }
    }
    
    static int StringToNumber(string str){
        switch(str){
            case "A":
