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。
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...
Its purpose is take the elements in 11th queue and divide them by ten and return them in a integer array.void back_to_ints(queue_t *arr[], int *new_arr) { queue_node_t *cur_nodep; cur_nodep = arr[10]->frontp; int i = 0, digit; while(cur_nodep != NULL){ cur_nodep->...
/* Simple Queue Static Simple queue demonstration using static queue data array LIFO / FIFO implementations can be tested by changing IMPLEMENTATION This example code is in the public domain. created 15 November 2022 by SMFSW */ #include <cQueue.h> #define IMPLEMENTATION LIFO typedef struct str...
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...

2.2.1 优先队列的使用(Using Priority Queues) C++标准库中的std::priority_queue可以用来管理优先级任务。它自动根据元素的优先级排序,每次从队列中取出时,都是优先级最高的任务。 2.2.2 处理不同优先级的任务(Handling Tasks with Different Priorities) ...
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 ...
2.1 接口与实现分离的原则(Principle of Separating Interface and Implementation) 接口与实现分离是实现代码结构解耦的基石。它的核心在于定义清晰、一致且稳定的接口,而将实现的细节隐藏起来。这样做不仅使得代码更加模块化,也使得系统更容易理解和维护。 2.1.1 抽象类和接口的作用(Role of Abstract Classes and Interf...
This is implemented by a modified queue called the circular queue. Complexity Analysis The complexity of enqueue and dequeue operations in a queue using an array is O(1). If you use pop(N) in python code, then the complexity might be O(n) depending on the position of the item to be ...
