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: Wrong Answer)

#include <iostream>
using namespace std;

int main(){
	char X[2];
	int Y[2], i=0;
	cin >> X[0] >> X[1];
	for(i=0;i<2;i++){
		if(X[i]='A') Y[i]=0;
		if(X[i]='B') Y[i]=1;
		if(X[i]='C') Y[i]=2;
		if(X[i]='D') Y[i]=3;
		if(X[i]='E') Y[i]=4;
		if(X[i]='F') Y[i]=5;
	}
	if(Y[0]<Y[1]) cout << "<" << endl;
	if(Y[0]>Y[1]) cout << ">" << endl;
	else cout << "=" << endl;
}
