java實現簡單石頭剪刀佈遊戲

Posted on by

本文實例為大傢分享瞭java實現簡單石頭剪刀佈遊戲的具體代碼，供大傢參考，具體內容如下

問題描述

Alice, Bob和Cindy一起玩猜拳的遊戲。和兩個人的猜拳類似,每一輪,他們會從石頭、剪刀、佈中各自選一個出拳,基本的勝負規則是石頭贏剪刀、剪刀贏佈、佈贏石頭。如果一輪中正好可以分成勝負兩邊,則負邊的每個人要支付給勝邊的每個人一塊錢。如果無法分成勝負兩邊,則都不出錢。比如,如果Alice出石頭,而Bob和Cindy都出佈,則Alice要分支付Bob和Cindy一塊錢。再如,如果Alice出石頭, Bob出剪刀, Cindy出佈,則都不出錢。他們三人共進行瞭n輪遊戲,請問最後每個人凈賺多少錢?即賺的錢減去支付的錢是多少?
