Question
What additional operations can be performed on a Doubly Linked List compared to a Singly Linked List?a)Inserting at the beginning only.b)Searching for an element.c)Traversing in both directions.d)Deleting at the end only.
Solution
The additional operations that can be performed on a Doubly Linked List compared to a Singly Linked List are:
c) Traversing in both directions: In a doubly linked list, we can traverse in both directions i.e., we can move to the next as well as the previous node. This is not possible in a singly linked list as it allows movement in one direction only.
The other operations mentioned:
a) Inserting at the beginning: This operation can be performed in both singly and doubly linked lists.
b) Searching for an element: This operation can also be performed in both singly and doubly linked lists.
d) Deleting at the end: This operation can be performed in both singly and doubly linked lists, but it's easier and more efficient in a doubly linked list because we can directly access the previous node, while in a singly linked list, we would need to traverse from the head node to the second last node.
