If these containers don't have to be arrays, investigate the NSSet.
Such operations are much more efficient on sets rather than iterating
through an entire array for every element in question from the other.

I don't believe there is. Write your own method and put it in a
category to
NSMutableArray. Enumerate through the second array using -
indexOfObject.
