Custom Doubly LinkedList Implementation


The doubly linked list is same as the linked list but every node has address of previous node also along with next node so that the traversal can be done in both ways.

To implement the custom doubly linkedlist, please follow below steps:
1. Create the basic structure class


2. Implement the doubly linkedlist operations


3. Test the functionality


Full implementation source code is as below:


Output:
23->34->65->78
-1->23->34->3478->65->78->6445
-1->23->34->3478->65->78
-1->23->34->3478->65
65->3478->34->23->-1
Prev::3478 & Curr::65
