【问题描述】：
我有一个脚本用于计算垒球（实际上是任何运动）的比赛对决。该脚本使用循环式计算来创建对决，以便每支球队至少与对方球队交手一次。此特定脚本允许您输入团队数量和游戏数量。根据比赛的数量，您可能会让球队互相比赛 2 或 3 次。因此，我还让脚本反转对战以模拟主客场比赛，因此如果比赛超过一次，任何球队都不会在主场占据优势。
当显示最终输出时，我的问题就出现了。我没有意识到对于每场“比赛”（所有球队的一系列对决），一些球队在同一场比赛/周中被列出两次。我们不希望任何球队在同一周/比赛中打两次。 在脚本中，我获取了一组比赛并将它们转换为一个哈希表，其中将比赛分组为球队数/2。
如何重新排列存在重复值的哈希表值并将它们与另一个“游戏”交换以创建没有团队玩两次的游戏（见下文）？
