The obvious way to represent sets in Erlang is as an unordered list of elements without duplication. The set manipulation functions are as follows: new() Returns an empty set. add_element(X, S) Adds an element X to the set S and returns a new set. del_element(X, S) Something shorter, and the lists don't even have to posses the same keys, and can be unordered: merge(In1,In2) -> Combined = In1 ++ In2, Fun = fun(Key) -> {Key,proplists:get_all_values(Key,Combined)} end, lists:map(Fun,proplists:get_keys(Combined)). Fun could be written directly in the lists:map/2 function, but this makes it readable.

Erlang lists

Lst − The list of elements which needs to be sorted.. Return Value. Returns a sorted list of elements. The following is a erlang function. I don't understand how lists:map function is used here.

Apply erlang:length/1 on each element of your list using lists:map/2: lists:map (fun erlang:length/1, [ [1, 2, 3], [], [4, 5]]) share. |. Sorts a list of elements.

An Erlang/OTP library for working with iterators; an opaque type that is evaluated as a lazily evaluated list of elements. This allows for memory efficient processing of sequential data and easy composition of processing on such lazy lists. Lists can thus be defined recursively as a head preceding a tail, which is itself a head followed by more heads.
