You should help Stephan write a function to calculate this "multiplication". You are given two positive integers (n > 0), be careful with order of arguments.

Input: Two arguments as integers.

Output: The result of the Stephan's "multiplication", an integer.

Example:

checkio(4, 6) == 38
checkio(2, 7) == 28
checkio(7, 2) == 18
    

How it is used: In this task we play around with logical binary operations, the basis for computer science. Maybe you can find a use for this subject in cryptography?

Precondition: 0 < x < 100
0 < y < 100
