用两个栈实现队列:https://leetcode.cn/problems/implement-queue-using-stacks/submissions/564009874/ 🌉stack的模拟实现 从栈的接口中可以看出,栈实际是一种特殊的vector,因此使用vector完全可以模拟实现stack。 stack.c 代码语言:javascript 代码运行次数:0 运行 AI代码解释 namespace own{template<classT>classsta...
我们做过一道相反的题目Implement Stack using Queues 用队列来实现栈。这道题颠倒了个顺序,起始并没有太大的区别,栈和队列的核心不同点就是栈是先进后出,而队列是先进先出,那么怎么用栈的先进后出的特性来表示出队列的先进先出呢?方法是:只要在插入元素的时候每次都从前面插入即可,即如果一个队列是1,2,3,4...

You should use a stack when you need to access elements in a LIFO manner, such as when implementing undo functionality, parsing expressions, or doing depth-first search in a graph. On the other hand, queues are better suited for scenarios where you need first-in-first-out (FIFO) access,...
Packets are forwarded through stack cables directly with packet priorities and queues unchanged. Mirroring Data packets forwarded through stack cables can be mirrored across switches using the mirroring function. The mirroring function cannot be configured on logical stack ports.
