Working with apriority_queueis similar to managing aheapin some random access container, with the benefit of not being able to accidentally invalidate the heap. 使用priority_queue容器和通过在随机访问容器上使用相关堆算法来管理堆数据所达到的效果是一致的,但是使用priority_queue优先级队列有一个好处是,不...

数据结构及算法基础--优先队列(Priority Queue) 这真的是一个包含很多东西的数据结构。我们会逐步解析,来讲解优先队列: 首先知道什么是优先队列: 普通的队列是一种先进先出的数据结构,元素在队列尾追加,而从队列头删除(first in, last out)。在优先队列中,元素被赋予优先级。当访问元素时,具有最高优先级的元素...
