Doubly Linked List and Circular Linked List

Question

Explain how the Doubly Linked List associated with the Circular Linked List?

Answer 1

The doubly linked list is a linked list in which each and every node knows where both of its neighbors are.

The circular linked list is a linked list in which the ‘tail’ of the list is linked to the ‘root’. (It is noted that both the tail and root of the list are undefined or arbitrary in a circular linked list)

Doubly linked lists are really not necessarily associated to circular linked list (aside from both being based on the linked list structure). However, you can have a circular doubly linked list, where each and every node knows where both of its neighbors are and where the list wraps around to join to itself.
