in Ruby: Write a method contains_pair_product? that takes in an array and a target number.

The method should return a boolean indicating whether or not a pair of elements of the array multiply together to result in the target.

p contains_pair_product?([1, 4, 3, 2], 8) #=> true

p contains_pair_product?([7, 5, 2, 4, 12], 12) #=> false
