    Elixir Template A) Use when there isn't a special first line

    defmodule Solution do
  def main() do 
    IO.read(:stdio, :all)
      |> String.split # lines
      |> Enum.map(&String.to_integer(&1)) # integers
      |> Enum.reverse() # reversed integers
      # remember IO.inspect's default limit is 50!
      |> Enum.each(&IO.inspect(&1, limit: :infinity))
  end
end

Solution.main()

    Elixir Template B) Use when there is a special first line

    defmodule Solution do
  def main() do 
    lines = IO.read(:stdio, :all)
      |> String.split
      
    [first_line | rest_lines] = lines
    
    delimiter = String.to_integer(first_line)
    items = Enum.map(rest_lines, &String.to_integer(&1))

    items
      |> Enum.filter(&(&1 < delimiter))
      |> Enum.each(&IO.puts(&1))
  end
end

Solution.main()

    Can you add Java 8?

    • astronomie + 1 comment

      Java 8 is not functional programming language

      • daily_spb + 1 comment

        But it handles functional programming, so it would be great to practice these skills with Java 8 instead of learning a brand new language for that reason.

          Having some functional constructs doesn't make java8 a functional language. Maybe a specialized section for java8 "functional thinking" is a better suggestion

    What is the point of this challenge? I literally just hit Submit on Haskell and got full marks.

    There was no challenge to this.

      i was looking at the code and although i don't know haskell it was somehow clearly complete, so i submitted and got the full score

      I spent ~20 minutes solving my own way, then saw this comment.

      I pressed Ctrl Z until I could no more, then pressed Run... I am kind of upset, lol.

      Thanks, tho!

      It is just to introduce you to their system. Many missing details and abiguous explanations exist in the site. These are in some way addressed by other aspects of the site which produce side effects which with time and effect you can learn about. Very distracting to have to waste time on this kind of useless learning. In real world problems there are better ways to understand the real meaning an item.

    Every comment here: Y NO JAVA/C?

    Because it's a domain for FUNCTIONAL programming!
