- 对于任意三个元素a、b和c,若 $comp(a, b)==true$ 且 $comp(b, c)==true$ 则需要满足 $comp(a, c)==true$参考文档:1. [C++中使用std::sort自定义排序规则时要注意的崩溃问题](blog.csdn.net/albertsh/)2. [cppreference](en.cppreference.com/w/c)...

2,4)同(1,3),但按照policy执行。这些重载仅若std::is_execution_policy_v<std::decay_t<ExecutionPolicy>>(C++20 前)std::is_execution_policy_v<std::remove_cvref_t<ExecutionPolicy>>(C++20 起)为 true 才参与重载决议。 参数 first, last-要排序的元素范围 ...

The range referenced must be valid; all pointers must be dereferenceable and within the sequence the last position is reachable from the first by incrementation. Elements are equivalent, but not necessarily equal, if neither is less than the other. Thesortalgorithm is stable and guarantees that ...
