What is the difference between a singly linked list and a doubly linked list?
- A doubly linked list is more memory-efficient than a singly linked list.
- A singly linked list allows traversal in both directions, while a doubly linked list allows traversal only in one direction.
- A singly linked list has nodes with pointers only to the next node, while a doubly linked list has nodes with pointers to both the next and the previous nodes.
- A singly linked list is limited to storing integers, while a doubly linked list can store any data type.
The main difference is that a singly linked list has nodes with pointers only to the next node, while a doubly linked list has nodes with pointers to both the next and the previous nodes. This allows for more flexible traversal in a doubly linked list.
