Difference between single and doubly linked list?Why do we prefer doubly over single linked list?

Question

Accepted Answer

Single linked list has one pointer while doubly linked list has two. Doubly linked list is preferred for easier traversal in both directions.

Single linked list has only one pointer which points to the next node while doubly linked list has two pointers which point to the next and previous nodes.
Doubly linked list allows for easier traversal in both directions, while single linked list only allows for traversal in one direction.
Doubly linked list requires more memory due to the extra pointer, but it allows for more efficient deletion and insertion operations.
Single linked list is simpler to implement and requires less memory, but it is less flexible than doubly linked list.
Examples of applications where doubly linked list is preferred include browser history, music playlists, and text editors.
