Welcome to the Bubble Sort in Elixir page! Here, you’ll find the source code for this program as well as a description of how the program works.
defmodule Bubble do @doc """ Sort the giveen input using bubble sort """ def main(args) do cond do length(args) != 1 or List.first(args) == "" or List.first(args) |> String.split(",") |> length < 2 -> IO.puts("Usage: please provide a list of at least two integers to sort in the format \"1, 2, 3, 4, 5\"") true -> input = List.first(args) |> String.split(",") |> Enum.map(&String.trim/1) |> Enum.map(&String.to_integer/1) sorted_list = pass(input, ) IO.puts(Enum.join(sorted_list, ", ")) end end @doc """ Handle each pass, return the list when there are no more changes to the list """ def pass(new_list, old_list) when new_list == old_list, do: new_list def pass(new_list, old_list) when new_list != old_list do passed_list = sort(new_list, ) pass(passed_list, new_list) end @doc """ Add the smaller element to accumulator, recursively call sort until all elements are added to accumulator """ def sort(, acc), do: acc def sort([head, tail], acc) do if head > tail, do: sort(, acc ++ [tail, head]), else: sort(, acc ++ [head, tail]) end def sort([head | [head2 | tail]], acc) do if head > head2, do: sort([head | tail], acc ++ [head2]), else: sort([head2 | tail], acc ++ [head]) end end Bubble.main(System.argv())
