Betaunordered_set 是 C++ 标准库中的一个无序关联容器，它存储的元素是唯一的，并且元素的插入、删除和查找操作平均时间复杂度为常数时间 O(1)（尽管在最坏情况下可能退化到 O(n)，但这在实际情况中很少发生）。 unordered_set 内部通常实现为一个哈希表，这意味着它不会根据元素的任何特定顺序来存储 ...

Betaset和map的区别就是set是K模型，而map是K/V模型. set. set模板中，第一个参数是 key的类型 ，第二个是一个仿函数，默认为 less ，即比根小放左边，比根大放右边，若传的是 greater<T>，则比根大的放左边 ， 比根小的放右边 。第三个参数即内存分配器，暂时不用管

BetaThis would at least give a compile time warning because the conversion of {true} to float is narrowing. I often put the braces around each function argument for added protection.
