此tic tac toe代码适用于除确定获胜者之外的所有内容。它可以确定一个平局，并很好地展示董事会。 我觉得问题在于从'check'方法返回变量'done'但我不知道是什么。我的返回语法生锈了所以我不确定我是否可以'记得如何访问返回的变量或者我被困住了什么。任何帮助是极大的赞赏。提前谢谢！

永远无法联系到显示代码的获胜者，因为player总是奇数或偶数 - 如果它不奇怪，那就是偶数。
答案 1 :(得分：0)
您的方法check（）无法正常工作。就像我一样，如果玩家赢了并观察check（）方法，请逐步调试代码。那些逻辑错误的东西。
尽管如此，就像Robin Green解释的那样：你的其他if（test ...）案例将永远不会达到，因为前两个if语句之一总是正确的。
