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 C++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<iostream>
#include<map>

using namespace std;

int main(){

	map<char,int>m;

	m.insert(make_pair('A',10));
	m.insert(make_pair('B',11));
	m.insert(make_pair('C',12));
	m.insert(make_pair('D',13));
	m.insert(make_pair('E',14));
	m.insert(make_pair('F',15));

	char X;
	char Y;

	cin >> X >> Y;

	int x = m.at(X);
	int y = m.at(Y);

	if(x < y){
		cout << "<";
	}else if(x > y){
		cout << ">";
	}else if(x == y){
		cout << "=";
	}

	return 0;
