ENQUEUE JAVASCRIPT ALGORIGHTM HOW TO

The following shows how to implement the queue data structure using an object: class Queue Code language: JavaScript ( javascript ) Summary Implementing a JavaScript queue using an object A queue works based on the first-in, first-out (FIFO) principle, which is different from a stack, which works based on the last-in, first-out (LIFO) principle. Introduction Many applications take advantage of multi-core computer architectures by ex-ecuting multiple tasks concurrently, often accessing shared data concurrently.Correctness of these data structures is ensured by synchronizing concurrent ac-cesses.

The customer who comes first will be served first, and the one who comes later is queued at the end of the queue and will be served later. Enqueue and dequeue operations can be runconcurrently, without misbehaving. The name queue comes from the analogy to a queue of customers at a bank. Different from the dequeue operation, the peek operation returns the element at the front without modifying the queue. The following picture illustrates a queue:Īnother important operation of a queue is getting the element at the front called peek. The algorithm is as follows : Step1: Create an adjacency list called graph Step2: Call the topologicalsorting () function Step2.1: Create a queue and an array called indegree Step2.2: Calculate the indegree of all vertices by traversing over graph Step2.

Remove an element from the front of the queue, which is called dequeue. Data Structures and Algorithms in JavaScript.Insert a new element at the end of the queue, which is called enqueue.

Queue data structure is used to implement FCFS CPU scheduling algorithm. Introduction to the Queue data structureĪ queue is an ordered list of elements where an element is inserted at the end of the queue and is removed from the front of the queue.Ī queue works based on the first-in, first-out (FIFO) principle, which is different from a stack, which works based on the last-in, first-out (LIFO) principle. Javascript Queue, operations of queue such as enqueue, dequeue, front, rear. Summary: in this tutorial, you will learn about the queue data structure and how to implement a JavaScript queue.
