I also like to check first if the key exists before fetching it as is shown in main/0 function. We do not need to exit early, so we can use lists:foreach/1 to iterate over the queries. The Erlang C formula is quite complex to look at, but can be straightforward to apply, if you follow these easy steps. We have also included a worked example in Excel to help you follow the maths.

This method is used to return all the keys from a map. 6: merge how to use erlang lists: map function The following is a erlang function. I don't understand how lists:map function is used here.

An example of how the Map data type can be used is shown in the following program. Here we are defining a Map M1 which has 2 mappings. The map_size is an inbuilt function defined in Erlang which can be used to determine the size of the map.
This structure is a finite mapping from keys to values with a flat internal representation: a map is essentially two arrays: one of double(L) -> map (fun (X) -> 2 *X end, L). add_one(L) -> map (fun (X) -> 1 + X end, L). map (F, List) is a function that takes a function F and a list L as arguments and returns a new list, obtained by applying F to each of the elements in L. An example of how the Map data type can be used is shown in the following program.
