大顶堆priority_queue <int,vector<int>,less<int> >q;//greater和less是std实现的两个仿函数(就是使一个类的使用看上去像一个函数。其实现就是类中实现一个operator(),这个类就有了类似函数的行为,就是一个仿函数类了)
void push(value_type&& _Val) { // insert element at beginning c.push_back(_STD move(_Val)); push_heap(c.begin(), c.end(), comp); } template<class... _Valty> void emplace(_Valty&&... _Val) { // insert element at beginning c.emplace_back(_STD forward<_Valty>(_Val)......
min_element返回两个索引之间最小元素的索引；iter_swap将最小索引和不停迭代的索引进行交换。 这就是...

push() inserts the element into the priority queue pop() removes the element with the highest priority top() returns the element with the highest priority size() returns the number of elements empty() returns true if the priority_queue is empty Insert Element to a Priority Queue We use the...
接下来,实现Queue协议: varisEmpty:Bool{returnheap.isEmpty}varpeek:Element?{returnheap.peek()}mutatingfuncenqueue(_element:Element)->Bool{// 1heap.insert(element)returntrue}mutatingfuncdequeue()->Element?{// 2returnheap.remove()} 1,在enqueue(_:)方法中,往heap中插入元素,会对元素进行上滤操作,使...

Thepriority queueis acontainer adaptorthat provides constant time lookup of the largest (by default) element, at the expense of logarithmic insertion and extraction. 优先级队列是一个提供常数时间查找容器内最大(默认情况下)元素以及在指数时间下插入和提取元素的容器适配器 ...
