我正在学习计算机科学入门课程，在下一个项目中，我应该做一个石头，纸，剪刀游戏。
游戏还没有结束，因为我仍然需要添加得分保持和输入建议（哦，我应该选择的次数更多）并循环播放。
但是我的问题是，我想测试游戏到现在为止是否正常运行。该代码可以正确编译，但是一旦我输入了我的决定并且计算机输入了它的决定，“赢家”就是不正确的。
例如：
玩家选择摇滚
计算机选择剪刀
这是TIE
我认为也许我输入了一些if语句，因为我选择的某些答案正确地出现了（关于谁是真正的赢家），有些则没有。
但是回到我的代码并多次检查所有代码之后，它们对我来说似乎是正确的...

同样，编码不完整。我仍然必须添加一些内容。
对不起，我还是编码新手。如果我对我的问题不够彻底或在代码页上添加的内容过多，请原谅我...我不知道要包括或排除哪些部分
