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.

        case 'A':return 10;
        case 'B':return 11;
        case 'C':return 12;
        case 'D':return 13;
        case 'E':return 14;
        case 'F':return 15;
        default:return 0;
    }
}
int main()
{
        char  x,y;
        scanf("%c %c",&x,&y);
        int a,b;
        a=toint(x);
        b=toint(y);
        if(a>b)
            printf(">\n%d>%d.\n",a,b);
        else if(a<b)
            printf("<\n%d<%d.\n",a,b);
        else
            printf("=\n%d=%d.\n",a,b);

    return 0;
