TI-BASIC:Rock Paper Scissors

Rock Paper Scissors is a classic game that involves two players choosing among three different hand gestures, and seeing who has the best hand. Each of the hand gestures -- rock, paper, and scissors -- beats one of the other two hand gestures, so there is a good likelihood that somebody will win. (However, if both players choose the same gesture, it is a tie.) You can play this game indefinitely, but it does get monotonous after a while.

Here is a handy table that tells which hand gesture wins in each situation:

!! Rock !! Paper !! Scissors
Rock	Tie	Paper	Rock
Paper	Paper	Tie	Scissors
Scissors	Rock	Scissors	Tie
