Recently, a Full-duplex asynchronous long connection communication component was developed in the project development, and the delay queue was used internally. and the delay queue of the internal implementation of storage is used to the priority

The precedence queue (priority_queue) is consistent with the function interface of the general queue (queue), and, in contrast, the priority queue is the smallest (or largest) element in the entire queue each time it is queued. This paper briefly

D-ary Heap Introduction: The D-ary heap is a generalized version of binary heap (d=2), and the D-ary heap has a maximum of D child nodes per non-leaf node. The D-ary heap has the following properties: Similar to complete binary tree, except

In the normal queue, the order of the elements out of the team is determined by the time the element is enqueued, that is, who first team, who first out. But sometimes we want to have such a queue: who first team is not important, what is important

The queue features FIFO. Generally, queues are similar to queuing for shopping. Everyone is very orderly. the first person in the queue buys something first. The priority queue is different. It does not follow the first-in-first-out rule, but is

Use of queue in java, and use of javaqueue At the same level as List and Set, the Queue interface inherits the Collection interface. The Queue List implements the Queue interface. The Queue interface narrow the access permission to the method of the
