The inverse of Interset

[Robert Sneidar]

To my knowledge you will need to convert the arrays to lists, work with them in that form and convert the resulting list to an array. I have a way to convert an array to a list which preserves the key names which may get you to that point, then a function to convert a list in that format back to an array. You will have to come up with the rest of the logic.
