HW impossibility?: “Create a rock paper scissors program in ruby WITHOUT using conditionals”

Question

I\'m in an introductory software development class, and my homework is to create a rock paper scissors program that takes two arguments (rock, paper), etc, and returns the arg t

Answer 1

I just think the simplest solution has to be something like:

@results = {
  'rock/paper' => 'paper',
  'rock/scissors' => 'rock',
  'paper/scissors' => 'scissors',
  'paper/rock' => 'paper',
  'scissors/paper' => 'scissors',
  'scissors/rock' => 'rock'
}

def winner p1, p2
  @results["#{p1}/#{p2}"]
end
