Mike likes to invent new functions. The latest one he has invented is called SuperFunction. Let's consider how it can be calculated: You are given two integers N and K. SuperFunction of N and K equals to the sum of K'th powers of the positive numbers, which are coprime with N and also not greater than N. I.e. SuperFuntion of 6 and 3 equals to 13 + 53 = 126. Mike knows how to calculate SuperFunc
