queue是一种先进先出(First In First Out,FIFO)的数据结构。它有两个出口,形式如下图所示 特点: queue允许新增元素、移除元素、从最底端加入元素、取得最顶端元素 但除了最底端可以加入、最顶端可以取出外,没有任何其他方法可以存取queue的其他元素。换言之queue不允许有遍历行为 将元素推入queue的动作称为push,将...
概念:Queue是一种先进先出(First In First Out,FIFO)的数据结构,它有两个出口 队列容器允许从一端新增元素,从另一端移除元素 队列中只有队头和队尾才可以被外界使用,因此队列不允许有遍历行为 队列中进数据称为 — 入队 push 队列中出数据称为 — 出队 pop queue 常用接口 功能描述:栈容器常用的对外接口 构...

搞一个优先队列维护一下事件结构体:时间,人的编号,入队还是出队 再维护两个setset,队列内的人inQueueinQueue,想要进入队列内的人wantwant 然后模拟模拟模拟! 初始把所有入队事件塞到优先队列,顺便维护一下当前最后一个取完水的时刻 每次取出优先队列里面时间最小的,时间相同优先取入队的,同时间都入队优先取编号小...
