/*
This program emulates the version of rock, paper, scissors popularized
by the tv series "Big Bang Theory". This variety utilizes the typical
rock, paper and scissors paradigm while adding lizard and spock to the
equation. (scissors > paper > rock > lizard > spock > scissors > lizard >
paper > spock > rock > scissors)

Thank you that cleaned up quite nicely! If you don't mind I will use your suggestions and give you credit of course. With a program this small I know that this is a non issue but since we're tuning things up how would you improve the time complexity?
I don't want to sound harsh, but that's some spaghetti code. There could be a mathematical way to judge the outcome or at least a vector of vectors of booleans to select the outcome from.
Yeah no worries haha, I have a whiteboard coming up in C++ and I haven't done anything with it for 3 years so I am just refreshing with a couple of tiny projects to keep my interest. But yes of course I am certain there are probably a thousand better ways to do it =)
