3. 队列的实现方式 (Implementation of Queue) 3.1 使用数组实现 (Using Array) 队列可以通过数组来实现,这是最常见的实现方式。数组是一种连续的内存结构,可以通过索引快速访问元素。但是,使用数组实现队列时,我们需要考虑队列的大小和如何处理队列的增长。 3.1.1 静态数组 (Static Array) 静态数组是固定大小的数组。
class CircularQueue {private:int *arr;int front, rear, size, capacity;public:CircularQueue(int cap) {capacity = cap;arr = new int[capacity];front = -1;rear = -1;size = 0;}// 入队 (Enqueue)void enqueue(int data) {if ((rear + 1) % capacity == front) {// 队列已满return;}if...
Ans. To insert an element into an array-based priority queue, you compare the priority of the new element with existing elements in the array, finding the appropriate position to maintain the priority order. The new element is inserted at that position, shifting other elements as necessary. Q3...
In the above implementation, to show that the queue is empty, bothrearandfrontindices are set to(-1). The execution starts from themain()function whereenqueue()function inserts a component to thequeue’srear by increasing therearindex while setting thequeuearray’s value at the newly createdr...
Implementation of Queue in C Queues in C can be implemented using Arrays, Lists, Structures, etc. Below here we have implemented queues usingArrays in C. Example: #include<stdio.h>#defineSIZE100voidenqueue();voiddequeue();voidshow();intinp_arr[SIZE];intRear=-1;intFront=-1;main(){intch...
5.1 顺序结构的实现 (Array-based Implementation) 栈是一种后进先出(LIFO)的数据结构,它只允许在栈顶进行插入和删除操作。顺序结构的栈,通常使用数组来实现。这种实现方式的主要优势是访问速度快,因为数组的元素在内存中是连续存储的。但是,它的大小是固定的,这可能会导致空间浪费或溢出。 const int MAX_SIZE = ...
The complexity of enqueue and dequeue operations in a queue using an array isO(1). If you usepop(N)in python code, then the complexity might beO(n)depending on the position of the item to be popped. Applications of Queue CPU scheduling, Disk Scheduling ...
When elements are added and removed often, a queue might be built as a circular queue to prevent wasting memory.Using Array:To implement a queue in C using an array, first define the queue's maximum size and declare an array of that size. The front and back integers were respectively set...
