- 游戏名称最多可以为31个字符
- 有三种游戏模式类别:主要、次要和杂项
- 只能选择1个主要游戏模式
- 某些主要游戏模式与某些次要游戏模式不兼容
- 某些次要游戏模式与其他次要游戏模式不兼容
- 杂项游戏模式可以与所有其他游戏模式组合使用
以下是各种游戏模式的列表,其中显示了每种模式与哪些次要模式兼容(X表示不兼容):

示例:这里有一些输入的示例,以及期望的输出:
"DotA v6.60 -RDSOSP USA/CA LC!" -> "rdsosp"
"DOTA AREMDM USA LC" -> "aremdm"
"DotA v6.60 -ApEmDuSpId USA BL" -> "apemduspid"
注意:解决方案不一定要提供实际代码,伪代码甚至只是解释如何处理都可以接受和优先考虑。此外,解决方案需要足够灵活,以便我能够轻松地添加另一个游戏模式。还可以安全地假设,在游戏名称中,游戏模式将始终从主要游戏模式开始。
