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 =.

=

15 = 15.

Solution in C (Clang 3.8.0) (judge verdict: Accepted)

#include <stdio.h>

int main(void)
{
    char ch[6] = "ABCDEF";
    char a, b;
    int n, m;

    scanf("%c %c", &a, &b);
    for (int i = 0; i < 6; i++){
        if (a == ch[i])
        n = i;
        if (b == ch[i])
        m = i;
    }

    if (n > m)
        printf(">");
    else if (n < m)
        printf("<");
    else if (n == m)
        printf("=");

    return 0;
}
