Doubly Linked Lists (DLL)
Learn the fundamentals of doubly linked lists, including their bi-directional node structure and efficient deletion methods. Understand how adding a previous pointer enhances traversal and makes managing nodes easier compared to singly linked lists.

Introduction #
By now, you must have noticed a constraint which arises when dealing with singly linked lists. For any function which does not operate at the head node, we must traverse the whole list in a loop.
While the search operation in a normal list works in the same way, access is much faster as lists allow indexing.
Furthermore, since a linked list can only be traversed in one direction, we needlessly ...
