一、priority_queue介绍priority_queue是一个拥有权值的queue,queue是先来的后出,而priority_queue是权值大的先出,具体可以查看如下的结构图:priority_queue的底层是依靠heap和vector实现的。 二、源码展示 C++ priority_queue用法 std::priority_queueC++ STL默认的priority_queue是将优先级最大的放在队列最前面,也即...

Under some reasonable assumptions, our priority queue supports minimum and insert in O(1) worst-case time and extract in O(N/S+lg S) worst-case time, where lg N ≤ S ≤ N/lg N. We also show how to use this data structure to simplify the existing optimal O(N~2/S + N lg S)...

It implements a max-priority-queue, and has three parameters: a comparison object for sorting such as a function object (defaults to less<T> if unspecified), the underlying container for storing the data structures (defaults to std::vector<T>), and two iterators to the beginning and end of...

Java PriorityQueue is an unbounded Queue implementation that processes the items based on priorities. Custom ordering can be enforced with a Comparator.
