Whether browsing forward or backward can be done using a singly linked
list. Is there any specific case where a doubly linked list is needed?
For people who say that singly linked list allows traversal only in one
direction, I would say that using appropriate loops/recursion, traversal
in opposite direction is also possible. Then why the need for doubly
linked list?
