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 =.
