You have an array of integers, and for each index you want to find the product of every integer except the integer at that index.

You have an array of integers, and for each index you want to find the product of every integer except the integer at that index.
Write a function get_products_of_all_ints_except_at_index() that takes an array of integers and returns an array of the products.

For example, given:

  [1, 7, 3, 4]
your function would return:

  [84, 12, 28, 21]
by calculating:

  [7*3*4, 1*3*4, 1*7*4, 1*7*3]
Do not use division in your solution.


#solution

def get_products_of_all_ints_except_at_index(arr)
final_arr = []
i = 0
total = 1
	while i < arr.length do 
		x = arr.slice(i)
		arr.each do |int|
			if int != x
			total = total * int
			end
		end
	final_arr << total
	i += 1
	total = 1
	end
