I have two arrays of different sizes.
Right now via find_all I can find all the elements that are common to
All the elements in the smaller arrays can be found in the larger array.
What I would like to find now is all th elements that are in the larger
array and missing on the smaller array.
I know I can iterate and compare each element within a nested loop.
But is there a way to print out the elements that are missing from the
smaller array without having to implement a nested loop?
