/* Hi! I am struggling with a program to play Rock Paper Scissors. I am confused about how to calculate wins, looses, and draws. My TA said I need to use return in PlayOneRound method, but I still can’t totally understand it and I am too guilty to bother her agian. Sorry for letting you face these ugly code.*/
