It is also used in algorithms of LRU (Least Recently used) and MRU(Most Recently Used) cache.The doubly linked list is used to implement data structures like a stack, queue, binary tree, and hash table.During the implementation of a hash function, there arises a problem of collision, to deal with this problem, a singly linked list is used.The undo or redo options, the back buttons, etc., that we discussed above are implemented using a singly linked list.The singly linked list is used to implement stack and queue.Circular linked lists can also be used to implement advanced data structures like MRU (Most Recently Used) lists and Fibonacci heap.The undo functionality that is present in applications like photo editors etc., is implemented using circular linked lists.In an operating system, a circular linked list can be used in scheduling algorithms like the Round Robin algorithm.In web browsers, the back button is implemented using a circular linked list.The circular linked list can be used to implement queues.You must be reading this article on your web browser, and in web browsers, we open multiple URLs, and we can easily switch between those URLs using the previous and next buttons because they are connected using a linked list.This feature is implemented using a linked list. We watch the photos on our laptops or PCs, and we can simply see the next or previous images easily.And these music players are implemented using a linked list. In music players, we can create our song playlist and can play a song either from starting or ending of the list.The linked list is also used in implementing graphs in which the adjacent vertices are stored in the nodes of the linked list popularly known as Adjacency list representation.Īpplications of Linked Lists in the Real World :.The linked list can be used to implement stacks and queues.Arithmetic operations like addition or subtraction of long integers can also be performed using a linked list.Using a linked list, we can perform the polynomial manipulation.Linked lists can be used to represent polynomials.Some of these Applications are :Īpplications of Linked List in Computer Science : There are many applications of linked lists, be it in computer science or the real world. What are the Applications of Linked List ? Linked lists do not use contiguous memory allocation for storage, unlike arrays. It is a collection of nodes, and a node contains data and addresses the next node. A linked list is a linear data structure.
