Question
Which type of linked list allows traversal in both forward and backward directions?a.Linear linked listb.Doubly linked listc.Singly linked listd.Circular linked list
Solution
The type of linked list that allows traversal in both forward and backward directions is b. Doubly linked list.
Here's why:
a. Linear linked list: This type of linked list only allows traversal in one direction, from the head node to the last node.
b. Doubly linked list: This type of linked list allows traversal in both directions. Each node in a doubly linked list has two links, one to the next node and another to the previous node.
c. Singly linked list: This type of linked list only allows traversal in one direction, from the head node to the last node.
d. Circular linked list: This type of linked list can be either singly or doubly linked, but they form a loop. This means you can traverse them indefinitely, but it doesn't mean you can go in both directions.
