What is the difference between a singly linked list and a doubly linked list?
- Both can traverse forward
- Doubly linked lists allow traversal in both directions
- Singly linked lists allow traversal in both directions
- Singly linked lists have less memory overhead
Singly linked lists only allow traversal in one direction, from head to tail, while doubly linked lists allow traversal in both directions, which enhances flexibility but comes with higher memory overhead.
