Create Rock Paper Scissors Using Pattern Matching

You’re going to recreate your rock paper scissors game using pattern matching.

In the Elixir cell below,

• Create a module RockPaperScissors
• Create a play/2 function that expects :rock, :paper, or :scissors for each parameter.
• play/2 should return "#{guess} beats #{guess}!" or "draw!" depending on the outcome.

RockPaperScissors.play(:rock, :paper)
":paper beats :rock!"

RockPaperScissors.play(:rock, :rock)
"draw!"

defmodule RockPaperScissors do
  def play(guess1, guess2) do
  end
end

Utils.feedback(:rock_paper_scissors_pattern_matching, RockPaperScissors)
