A Queue can be implemented in many ways using arrays,linked lists, Pointers and Structures. But for some simplicity’s sake, we should implement it using the single-dimensional or one-dimensional array. Before going into detail, we should have prior knowledge of when to use the current data ...
1. Queue Array Basic OperationsWrite a C program to implement a queue using an array. Programs should contain functions for inserting elements into the queue, displaying queue elements, and checking whether the queue is empty or not. Sample Solution:...
using System; using System.Collections; namespace CollectionsApplication { class Program { static void Main(string[] args) { Queue q = new Queue(); q.Enqueue('A'); q.Enqueue('M'); q.Enqueue('G'); q.Enqueue('W'); Console.WriteLine("Current queue: "); foreach (char c in q) Co...
using System;using System.Collections;classProgram{staticvoidMain(){// 创建一个原始Queue并入队一些元素Queue originalQueue=newQueue();originalQueue.Enqueue("Element 1");originalQueue.Enqueue("Element 2");originalQueue.Enqueue("Element 3");// 使用ToArray方法创建副本Queue copiedQueue=newQueue(originalQ...
* ArrayBlockingQueue :一个由数组支持的有界队列。 * LinkedBlockingQueue :一个由链接节点支持的可选有界队列。 * PriorityBlockingQueue :一个由优先级堆支持的无界优先级队列。 * DelayQueue :一个由优先级堆支持的、基于时间的调度队列。 * SynchronousQueue :一个利用 BlockingQueue 接口的简单聚集(rendezvous)...
入队:容量够,放在数组_tail标处,同时 _tail = (_tail + 1) % _array.Length,可能导致_head > _tail,后面如需扩容时分两步,先先复制头到数组size-1标,再复制数组0标到尾;容量不够,先扩容 // Adds obj to the tail of the queue. //

使用CMake的编译命令: cd lock_free_stack # 只执行一次 mkdir build cd build cmake .. && make 运行结果如下: ./lock_free_stack The data 0 is pushed in the stack. The data 1 is pushed in the stack. The data 2 is pushed in the stack. The data 3 is pushed in the stack. The data...
