File Types

Create a FileTypes module which can display the number of files of a given type in a folder.

For example, we have create a file_types folder with several files inside of it.

File.ls!("data/file_types")

Provided a folder, your FileTypes module should return the number of files by their extension.

[txt: 2, ex: 2, png: 1, jpg: 1] = FileTypes.find("data/file_types")

Enter your solution below.

defmodule FileTypes do
  def find(folder) do
  end
end
