std::map 是一種有序關聯容器,它包含具有唯一鍵的鍵值對。鍵之間以比較函數 Compare 排序。搜索、移除和插入操作擁有對數複雜度。map 通常實現為紅黑樹。 std::map 的迭代器以升序迭代各鍵,此升序由構造時所用的比較函數定義。就是說,給定 m,一個 std::map it_l 和it_r,m 的可解引用迭代器,且 it...

可以搜索一下 vector 的底层实现方法 >set(及 multiset) 可以重点关注.lower_bound(...)等成员函数,及迭代器的用法 >map 可以关注 元素的插入删除机制 以及operator[] >deque 可以常数时间下标访问,但是内存不连续 >priority_queue 可以了解如何修改或自定义比较函数,例如priority_queue<T, vector<T>, greater<T...
