Gen_byte is generating two random bits 00,01,10 (not 11) for a rock paper scissors game. 00 is rock, 01 is paper and 10 is scissors. This play_game function is checking if player 1 wins, looses or ties. The problem is that when I run the test the output goes like WLTWLTWLTWLT… and doesn’t stop. I’m not quite sure where the problem is.

Play the game once, that is

(1) compute two moves (RPS) for the two computer players

(2) Print (W)in (L)oss or (T)ie, whether the first player wins, looses or ties.

Returns: Nothing, only print either character ‘W’, ‘L’, or ‘T’ to stdout
