I have seen lots of solutions confusepriority queuewithheap. I find a goodlinkand list the talk below. Concept: 1.Heapis a kind ofdata structure. It is a name for a particular way of storing data that makes certain operations very efficient. We can use a tree or array to describe it....

Priority Queue利用Min Quadruple Heap来实现投递元素按照优先级的顺序来执行。 1. Delaying Queue 1.1 Delaying Queue 介绍 Delaying Queue是一个延迟队列,它的特点是:投递的元素会在指定的时间到期后才会被执行。 由于Delaying Queue是从Queue派生的,所以它具备Queue的所有功能,也就是说Delaying Queue继承Queue所有接口...
heap_size = heap_size_; } // priority queue int heapMaximum() { return number[1]; } int heapExtractMax() { assert(heap_size>=1); int max = number[1]; //move the last value to root, then adjust to heap number[1] = number[heap_size]; ...
0.0、首先注意一点,priority_queue没有front()方法,和一般的queue不一样,与这个方法对应的是top() 0.1默认的: 它的模板声明带有三个参数,priority_queue<Type, Container, Functional> Type 为数据类型, Container 为保存数据的容器, Functional 为元素比较方式。
