Given an array of numbers, return array of products of all other numbers
Given an array of n integers, return an array of same size such that prod[i] is equal to the product of all the elements of arr except arr[i].
- Not allowed to use division operator
- Max Time complexity should be O(n)
data = [ 1, 2, 3, 4 ]
prod = [24, 12, 8, 6]
