Hi all, How can returnList be generated in a functional way?

You can do this using filter for section and flatMap.
But your imperative implementation has better performance than possible functional ones

Thanks Andrey, what would flatMap part look like?

You also can omit .toList(), depends on case, but because your mutable list is not cached, you can return it without protective copy
