栈stack,又称堆栈,是运算受限的线性表。简单来说:采用栈结构的集合,对元素的存取要求为【先进后出】可以简洁明了用下图说明: 队列 queue,简称队,也是一种运算受限的线性表,仅允许在表的一端进行插入,另一端进行删除。对元素的存取要求为【先进先出】,和栈相反,如下图: 数组 Array,是有序的元素序列,是在内存...

给出push,pop操作对应的序列,判定是stack, queue还是deque。用上面三个数据结构对应模拟下push,pop的操作,将结果与输出进行比对,需要注意的是如果pop一个空的数据结构时,以上三者就都不是了。#include #include #include # 阅读全文 posted @ 2013-08-16 11:59 litstrong 阅读(303) 评论(0) 推荐(0) SGU...
We dont have to scan all the vertices everytime, we simply find the ones with in-degree 0, and put them into a queue (or stack, both will work), and decrease their children in-degree by 1, then we dequeue the first node (or pop) and search if the children’s in-degree is 0....
