In a doubly linked list, what happens to the previous pointer of the head node after inserting a new node at the beginning?
In a doubly linked list, what happens to the previous pointer of the head node after inserting a new node at the beginning?
- It points to the new node.
- It remains `NULL`. (correct)
- It points to itself.
- It points to the last node of the list.
What is the primary advantage of using a circular linked list over a singly linked list in specific applications?
What is the primary advantage of using a circular linked list over a singly linked list in specific applications?
- Easier implementation of deletion operations.
- More efficient memory usage.
- Ability to traverse the list from any point without reaching a `NULL` end. (correct)
- Faster element access.
Which of the following scenarios is best suited for using a linked list instead of an array?
Which of the following scenarios is best suited for using a linked list instead of an array?
- When you need to access elements frequently using their index.
- When frequent insertions and deletions are required, especially in the middle of the list. (correct)
- When the size of the data structure is known and fixed.
- When memory usage must be minimized at all costs.

Linked List
Linked List
A linear data structure where elements are stored in nodes, each containing data and a pointer to the next node.
Singly Linked List
Singly Linked List
Each node points only to the next node in the sequence.
Doubly Linked List
Doubly Linked List
Each node points to both the next and previous nodes, allowing bidirectional traversal.
