What are advantages and disadvantages of doubly linked list?
What are Advantages and Disadvantages of Doubly Linked List. Advantages: 1. We can traverse in both directions i.e. from starting to end and as well as from end to starting. 2. It is easy to reverse the linked list. 3. If we are at a node, then we can go to any node. But in linear linked list, it is not possible to reach the previous node.

What is double linked list?
Doubly Linked List. Definition – What does Doubly Linked List mean? A doubly linked list is a linked list data structure that includes a link back to the previous node in each node in the structure.
