说明：  你将实现两个玩家版本。一名玩家将是计算机，另一名玩家是您程序的用户。让我们将电脑玩家称为机器人和用户玩家作为人。你可以假设机器人总是处理这些卡片。
(You will implement two player versions. One player will be a computer and the other player will be the user of your program. Let's call computer players robots and user players as people. You can assume that the robot always handles these cards.)
