WebJul 28, 2024 · The nodes in a linked list are connected through pointers. Pointers represent the address of a location in a memory. The order in a linked list is determined by a pointer in each node. A node in a doubly linked list contains a data item and a node pointer to the next node. In a singly linked list we can traverse only in one direction.

WebThe crux of this article is that a doubly linked list has a similar behaviour as a singly list most of the time. However, there are a few cases when a double list performs better than a singly linked list. Insertion and deletion operations are easier and more efficient in a doubly-linked list as compared to a singly linked list.
