module Data.Set
distrib :: Ord a => Set (Set a) -> Set (Set a) -> Set (Set a) Source #
distrib {a, b, c} {d, e, f} -> {a+d, a+e, a+f, b+d, b+e, b+f, c+d, c+e, c+f}
cartesianProduct :: Set a -> Set b -> Set (a, b) #
Calculate the Cartesian product of two sets.
cartesianProduct xs ys = fromList $ liftA2 (,) (toList xs) (toList ys)
Example:
cartesianProduct (fromList [1,2]) (fromList [a,b]) = fromList [(1,a), (1,b), (2,a), (2,b)]
