Day 17: More Exceptions

• Instructions:
  • Write a Calculator class with a single method: int power(int,int)
  • The power method takes two integers n & 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
