"""
Write a Calculator class with a single method: int power(int,int). The power method takes two integers, 
n and p, as parameters and returns the integer result of n**p. If either n or p is negative,
then the method must throw an exception with the message: n and p should be non-negative.

Note: Do not use an access modifier (e.g.: public) in the declaration for your Calculator class.
