How can I use functors or applicatives to rewrite this Haskell function over lists of tuples

in Education by
Is there a nicer way to write the following function fs' with functors or applicatives? fncnB = (* 2) fncnA = (* 3) fs' fs = zip (map (fncnA . fst) fs) $ map (fncnB . snd) fs I see from this question that I could rely on the functor instance of lists to map a single function acting over both elements of each tuple, or e.g. on the applicative instance of tuples to apply functions to just the second-half of a two-tuple, but I'm curious how functors and applicatives fit into the picture of operating over lists of multi-component data types.

A tuple is a bifunctor, so bimap is available. import Data.Bifunctor fncnB = (* 2) fncnA = (* 3) fs' = map (bimap fncnA fncnB) No third-party libraries required.
