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:...
object[] array = queue.ToArray(); Console.WriteLine($"Array Length: {array.Length}"); // 输出:2 } }实例2 using System; using System.Collections; namespace CollectionsApplication { class Program { static void Main(string[] args) { Queue q = new Queue(); q.Enqueue('A'); q.Enqueue...

Sample Solution: C Code: #include <iostream> #include <stack> using namespace std; const int MAX_SIZE = 100; class Queue { private: int front; // Front index of the queue int rear; // Rear index of the queue int arr[MAX_SIZE]; // Array to store elements public: Queue() { fro...
siftUpComparable(n, e, array); else siftUpUsingComparator(n, e, array, cmp);// 支持优先级排序 size = n + 1; notEmpty.signal(); } finally { lock.unlock(); } return true; } PriorityBlockingQueue是一个带优先级的 队列,而不是先进先出队列。元素按优先级顺序被移除,该队列也没有上限(看...
在C#中,可以使用Queue类的构造函数或ToArray方法来创建一个队列的副本。以下是两种方法的示例代码和讲解: 使用构造函数: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 using System;using System.Collections;classProgram{staticvoidMain(){// 创建一个原始Queue并入队一些元素Queue originalQueue=newQueue();...
#include <iostream>#include<queue>#include<vector>usingnamespacestd;intmain() { priority_queue<pair<int,int> >a; pair<int,int> b(1,2); pair<int,int> c(1,3); pair<int,int> d(2,5); a.push(d); a.push(c); a.push(b);while(!a.empty()) ...
(一)RingBuffer(ArrayLockFreeQueue) 下面我们来看基于循环数组的无锁队列,也就是RingBuffer如何解决多线程竞争的问题。 首先看下RingBuffer的数据结构如下: 14 template <typename ELEM_T, QUEUE_INT Q_SIZE = ARRAY_LOCK_FREE_Q_DEFAULT_SIZE> 15 class ArrayLockFreeQueue ...
Object[] array=queue;//将头节点取出返回E result = (E) array[0];//将末尾节点当做向头节点位置存入的节点E x =(E) array[n]; array[n]=null; Comparator<?superE> cmp =comparator;if(cmp ==null) siftDownComparable(0, x, array, n);elsesiftDownUsingComparator(0, x, array, n, cmp); ...
