Finger Exercise Lecture 4

Assume you are given a positive integer variable named N. Write a piece of Python code that finds the cube root of N. The code prints the cube root if N is a perfect cube or it prints error if N is not a perfect cube. Hint: use a loop that increments a counter—you decide when the counter should stop.
