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)
Insert element(public member function) pop Remove top element(public member function) priority_queue是一种容器适配器。容器适配器的意思就是说其底层实现依赖于某一特定容器,使用该容器来存储数据。容器适配器只是对该容器的一层封装,以满足上下文应用的需要。容器适配器对其成员函数的调用最终是对容器的函数的调用。
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...
// Retrieve the top element without removing it inline Label* top() const { debug_assert(size_ > 0); return elts_[0]; } // Get the number of elements stored within inline auto size() const { return size_; } // Check whether the priority queue is empty inline auto empty() const...
In C++, thepriority_queueclass provides various methods to perform different operations on a queue. Insert Element to a Priority Queue We use thepush()method to insert an element into the priority queue. For example, #include<iostream>#include<queue>usingnamespacestd;intmain(){// create a qu...
I need to use a concurrent priority queue for extracting min-values elements. I know that in my domain, during a pushback of an element it is assured that the element's value is greater than all values of elements in the queue prior to the pushback operation. Can I...

Inserts the specified element into this priority queue. Offer(Object) Inserts the specified element into this priority queue. Peek() Retrieves, but does not remove, the head of this queue, or returns null if this queue is empty. Poll() Retrieves and removes the head of this queue, or...
After a pop, the element at the top of the priority_queue is 20. priority_queue::priority_queue priority_queue建構空的 ,或是基底容器物件或另一個 priority_queue的複本。 C++ 複製 priority_queue(); explicit priority_queue(const Traits& _comp); priority_queue(const Traits& _comp, const ...
