list即环状双向链表,即Circular Double Linked List。 list的继承层次 list定义在stl_list.h 中,它的继承关系如下所示: list-> _List_base [_List_impl -->_Node_alloc_type] list继承自_LIst_base,而_List_base内含了一个_List_impl类,而_List_impl继承自_Node_alloc_type。 _Node_alloc_type是allocator...
3 搜索一个元素需要对数时间。 搜索一个元素需要线性时间。 4 元素是唯一的。 可能包含重复的元素。 5 只能包含一个空值。 可以包含一个以上的空值。 6 插入和删除需要对数时间。 插入和删除需要恒定的时间。 7 在HashSet, LinkedHashSet, 和TreeSet中实现。 在ArrayList和LinkedList中实现。上...
it = c1.insert(it,200);//在it前插入元素200//c1 = {200,100, 100, 100}c1.insert(it,2,300);//在it前插入两个元素值都为300//c1 = {300,300,200,100, 100, 100}// 将 it 重新指向开头it = c1.begin();std::list<int>c2(2,400);//c2 = {400, 400}c1.insert(std::next(it,...

The forward_list class template has been designed with efficiency in mind: By design, it is as efficient as a simple handwritten C-style singly-linked list, and in fact is the only standard container to deliberately(从容的) lack(缺乏) a size member function for efficiency considerations: due...
