A queue is a useful data structure in programming. It is similar to the ticket queue outside a cinema hall, where the first person entering the queue is the first person who gets the ticket. Queue follows the First In First Out (FIFO) rule - the item that goes in first is the item...
从队列中删除元素称为离队或出队,元素出队后,其后续元素成为新的队首元素。队列的结构示意图,如下所示: 由于队列的插入和删除操作分别在队尾和队首进行,每个元素必然按照进入的次序离队,因此,队列也称为先进先出表(First In First Out,简称 FIFO)。 2、队列的分类 2.1 按线性表的存储结构 由于队列也是一种线...
