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 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 JavaScript Program for Implementation of Queue using Linked List A queue is a linear data structure that follows the First In, First Out, FIFO principle, where elements are added at the rear and removed from the front. We must implement a queue data structure using a linked list and provide operations such as enqueue, dequeue, peek, and isEmpty. Linked list-based 2 min read Java Program to Implement the Queue Data Structure Queue is the fundamental data structure that follows the First-In-First-Out(FIFO) principle where the element that is inserted first is one that gets removed first. Imagine the queue of the people waiting in the line at the ticket counter: the person who arrives the first gets served first and so on 4 min read Queue Interface In Java The Queue Interface is a part of java.util package and extends the Collection interface. It stores and processes the data in order means elements are inserted at the end and removed from the front. Key Features:Most implementations, like PriorityQueue, do not allow null elements.Implementation Class 11 min read Difference between PriorityQueue and Queue Implementation in Java Java Queue InterfaceThe Java.util package has the interface Queue, which extends the Collection interface. It is employed to preserve the components that are handled according to the FIFO principle. It is an ordered list of items where new elements are added at the end and old elements are removed f 5 min read Queue Implementation Using Linked List in Java Queue is the linear data structure that follows the First In First Out(FIFO) principle where the elements are added at the one end, called the rear, and removed from the other end, called the front. Using the linked list to implement the queue allows for dynamic memory utilization, avoiding the cons 4 min read Queue meaning in DSA A Queue is defined as a linear data structure that is open at both ends and the operations are performed in the First In First Out (FIFO) order. Queue Data StructureCharacteristics of Queue:The first item added to the queue is the first one to be processed (or can be firstly deleted/removed), and su 3 min read Queue offer() method in Java The offer(E e) method of Queue Interface inserts the specified element into this queue if it is possible to do so immediately without violating capacity restrictions. This method is preferable to add() method since this method does not throws an exception when the capacity of the container is full s 5 min read Like
