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 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
int main(void)
{
	char x,y;
	int X,Y;
	int a=10,b=11,c=12,d=13,e=14,f=15;
	while(scanf("%c %c",&x,&y)!=EOF)
	{
		if(x=='A')
			X=a;
		if(x=='B')
			X=b;
		if(x=='C')
			X=c;
		if(x=='D')
			X=d;
		if(x=='E')
			X=e;
		if(x=='F')
			X=f;	
		if(y=='A')
			Y=a;
		if(y=='B')
			Y=b;
		if(y=='C')
			Y=c;
		if(y=='D')
			Y=d;
		if(y=='E')
			Y=e;
		if(y=='F')
			Y=f;
		if(X<Y)
			printf("<\n");
		if(X>Y)
			printf(">\n");
		if(X==Y)
			printf("=\n");				
	}
	return 0;
