C program to create and traverse Doubly Linked List.
Doubly Linked List: Create and display a doubly linked list: ----- Input the number of nodes: 3 Input data for node 1: 2 Input data for node 2: 5 Input data for node 3: 8 Data entered on the list are: node 1: 2 node 2: 5 node 3: 8 Flowchart: DlListcreation(): displayDlList(): C Programming Code Editor: Have another way to solve this solution?

Doubly linked list is a type of linked list in which each node apart from storing its data has two links. The first link points to the previous node in the list and the second link points to the next node in the list. The first node of the list has its previous link pointing to NULL similarly the last node of the list has its next node pointing to NULL.
Insertion At Last in doubly linked list create a new node and address in assigned to ptr.
Doubly Linked List: Insert new node at the middle in a doubly linked list: ----- Input the number of nodes (3 or more ): 3 Input data for node 1: 2 Input data for node 2: 4 Input data for node 3: 5 Data entered in the list are: node 1: 2 node 2: 4 node 3: 5 Input the position ( 2 to 2 ) to insert a new node: 2 Input data for the position 2: 3 After insertion the new list are: node.
Unlike a single linked list, the doubly linked list can be traversed and searched in both directions. The reference to the next node helps in traversing the node in the forward direction while the references to the previous nodes allow traversal in the backward direction. Basic operations such as insertion and deletion are easier to implement in the doubly linked lists since, unlike single.
In the given doubly linked list, delete a node. We can delete head node, middle node or last node. Example. Algorithm. Time complexity: O(1) Step 1: create a function which takes a linked list and node that had to be deleted as arguments and delete the node. Step 2: If you want to delete a head node. a) Change the head pointer to next of current node (head here). b) Change the previous.
Linked List is a data structure consisting of a group of vertices (nodes) which together represent a sequence. Under the simplest form, each vertex is composed of a data and a reference (link) to the next vertex in the sequence.
