Double linked list program in c code

Similar to insertion, we can also delete a node from 3 different positions of a doubly linked list. And, the final doubly linked list looks like this. In this case, we are deleting the last node with value 3 of the doubly linked list. Course Index Explore Programiz. Start Learning DSA. Popular Tutorials Quicksort Algorithm.

The push must receive a pointer to the head pointer, because push must change the head pointer to point to the new node See this Following are the 5 steps to add node at the front.

Four steps of the above five steps are same as the 4 steps used for inserting at the front in singly linked list. The only extra step is to change previous of head. Since a Linked List is typically represented by the head of it, we have to traverse the list till end and then change the next of last node to new node. Following are the 7 steps to add node at the end. Skip to content. Change Language. Related Articles. Table of Contents. Improve Article. Save Article. Like Article.
