2. Queue(队列) Queue和Stack有一些类似,不同的是Stack是先进后出,而Queue是先进先出。Queue在生活中的例子比如排队上公交,排在第一个的总是最先上车;又比如打印机的打印队列,排在前面的最先打印。 Queue一般具有以下常见方法: enqueue:入列,向队列尾部增加一个元素 dequeue:出列...

Pass an options object after the job argument in the Queue.add() method. Some of the job options properties are: priority: number - Optional priority value. Ranges from 1 (highest priority) to MAX_INT (lowest priority). Note that using priorities has a slight impact on performance, so ...

tree是一种多层数据结构,与Array、Stack、Queue相比是一种非线性的数据结构,在进行插入和搜索操作时很高效。 一个二叉查找树应该具有以下常用方法: add:向树中插入一个节点 findMin:查找树中最小的节点 findMax:查找树中最大的节点 find:查找树中的某个节点 isPresent:判断某个节点在树中是否存在 remove:移除树...
