DLL can be considered as a variation of the singly linked list. It has two pointers namely next and previous. Linked Link Doubly Linked Listĭoubly linked list or more commonly referred to as DLL is similar in node structure as that for a singly linked list except for the fact that they have an extra pointer which is used for back traversal on the list. A basic C++ structure of node in a singly linked list is shown below. Linked lists can be classified as Singly, Doubly and Circular Linked lists. Converting a linked list to other forms of non-linear data structures like trees is also possible.Other linear data structures like stacks and queue can also be implemented using linked lists.Insertion and deletion in arrays require shifting of nodes.

Insertion and deletion of nodes in a linked list are easier.A linked list is dynamic in nature, which means it can grow and shrink at runtime.Here are some points that make a linked list better than arrays. Each node consists the type of data it stores and a reference to the next node. Linked list are linear data structures that has a collection of nodes connected to each other. Each node contains three fields: two link fields and one data field. It is a linked data structure that consists of a set of sequentially linked records called nodes. How data structures are compiled can also be a deciding factor for their categorization.īefore learning about the features, let us understand what Doubly Linked List is.

Data Structures can also be categorized as Homogeneous and Non-Homogeneous depending on whether the data stored in a repository is of the same type or not. Each data structures contain information about the type of data it stores, the relationship between data and operations allowed on the data structure. Linear data structures include arrays, stacks, queues, and linked lists. Data structures may be linear or non-linear depending on whether they store data sequentially or not. Data structures are a way of storing and retrieving data in an efficient manner.
