What’s the best way you can check if one list is a subset of another list?
I.e. that all the elements of List_1 are in List_2
Bonus points if you can display which element is missing:
I’d love to see better implementations than what I have. Good luck!
(Note, if you’re going to do this don’t forget that an empty cell is not really empty, it actually contains a “”, which counts as an element. That can mess you up if you’re not aware.)
