            This problem was asked by Uber.
            Given an array of integers, return a new array such that each element at index i of the new array is 
            the product of all the numbers in the original array except the one at i.
            For example, if our input was [1, 2, 3, 4, 5], the expected output would be [120, 60, 40, 30, 24]. 
            If our input was [3, 2, 1], the expected output would be [2, 3, 6].
            Follow-up: what if you can't use division?
