Cheat at Rock-Paper-Scissors-Lizard-Spock When playing Rock-Paper-Scissors-Lizard-Spock, your robot reflexes let you see your opponent's throw before they make it. You just need to choose a throw that beats theirs, in as few bytes as possible of course. 

There's always two winning throws, and either one will work.



Input    -&gt; Possible outputs
------------------------------

Spock    -&gt; Paper or Lizard
Paper    -&gt; Lizard or Scissors
Lizard   -&gt; Scissors or Rock
Scissors -&gt; Rock or Spock


Take a string as input, and output one of the strings that beats it. Strings must be exactly as given, with capitalization. List of characters may substitute for strings.

Gets each output based on the length of the input modulo 4. I think this is probably the optimal strategy.
