I have two sets of items. Every item has a score. I'm finding the sum of the scores of the items of the intersection of both sets.
What would the best way to notate this be?
An example:
A = {a, b, c, d} B = {c, d, e} The scores are: a -> 9 b -> 8 c -> 7 d -> 6 e -> 5 The result is the sum of the values of c and d, 7 + 6 = 13
