unionLists :: (Outputable a, Eq a) => [a] -> [a] -> [a] Source #
minusList :: Ord a => [a] -> [a] -> [a] Source #
Calculate the set difference of two lists. This is O((m + n) log n), where we subtract a list of n elements from a list of m elements.
Extremely short cases are handled specially: When m or n is 0, this takes O(1) time. When m is 1, it takes O(n) time.
