A doubly linked list is a linear data structure, in which the elements are stored in the form of a node. Each node contains three sub-elements. A data part ...
1. Firstly, we will Create a Node class that represents a list node. It will have three properties: data, previous (pointing to the previous node), and next (pointing to the next node). 2. Create a new class that will create a doubly linked list with two nodes: head and tail. The...
*next - address of next node A doubly linked list node Note: Before you proceed further, make sure to learn about pointers and structs. Representation of Doubly Linked List Let's see how we can represent a doubly linked list on an algorithm/code. Suppose we have a doubly linked list: ...

Node in Double Linked List: Prev NodeDataNext Node Here Prev Node and Next Node are pointers to previous and next elements of node respectively. ‘Data’ is the actual element where data is stored. Below are some of the important terms we need to understand, ...
