A Heap is a specialized tree-based structure that allows for quick retrieval of the smallest or largest element, making it useful for priority queues, scheduling algorithms, and graph algorithms l 2 min read Implementation of Priority Queue in Javascript Priority Queue is an extension of Queue having some properties as follows: Each element of the priority queue has a priority associated with it.Elements are added to the queue as per priority.Lowest priority elements are removed first.We can design a priority queue using two approaches in the first 9 min read Implementation of Queue in Javascript A Queue is a linear data structure that follows the FIFO (First In, First Out) principle. Elements are inserted at the rear and removed from the front.Queue Operationsenqueue(item) - Adds an element to the end of the queue.dequeue() - Removes and returns the first element from the queue.peek() - Ret 7 min read p5.js | Dequeue Operation in Queue What is Queue? A Queue is a linear structure which follows a particular order in which the operations are performed. The order is First In First Out (FIFO). A good example of a queue is any queue of consumers for a resource where the consumer that came first is served first. It takes constant time t 4 min read JavaScript program to implement queue using stack A queue is a First In First Out (FIFO) data structure, in which the first element added to the queue is the first one to be removed. The different operations associated with Queue include Enqueue, Dequeue etc. A stack is a Last In, First Out (LIFO) data structure, in which the last element added to 3 min read JavaScript program to implement stack using queue In this article, we implement a JavaScript program to make a stack using a queue data structure. It provides essential stack methods like push(), pop(), and peek(), isEmpty() operations, utilizing either one or two queues to simulate the behavior of a stack. Examples: Input:push(2)push(3)pop()peek() 4 min read p5.js | Enqueue Operation in Queue What is Queue? A Queue is a linear structure which follows a particular order in which the operations are performed. The order is First In First Out (FIFO). A good example of a queue is any queue of consumers for a resource where the consumer that came first is served first. It takes constant time t 3 min read JavaScript program to Implement a Circular Queue using Arrays A circular queue is a roundabout. When the last person in line is served, they go back to the start of the line. This way, there's no wasted space and the line keeps moving efficiently. It is an extended version of a conventional queue, a circular queue is created by joining the last element to the 3 min read Implement enqueue and dequeue using only two stacks in JavaScript ? In this article, we will implement queue's operations (enqueue and dequeue) using only two stacks (in the form of plain arrays) in JavaScript. Before directly jumping into understanding the problem statement let us understand briefly what exactly a stack is and also what exactly a queue is. A stack 6 min read PHP DsQueue Functions Complete Reference A Queue is a linear data structure that follows a particular order in which the operations are performed.
