In linked lists there are no NULL links in:Question 11Select one:a.Single linked listb.Linear doubly linked listc.Circular linked listd.None of these

Understanding the Question

The question asks about linked lists that do not contain NULL links. In linked lists, the presence of NULL links typically denotes the end of the list or a break in the chain of nodes.

Analysis of Options

1. Single Linked List: In a single linked list, the last node points to NULL indicating the end of the list.
2. Linear Doubly Linked List: Similar to a single linked list, it has NULL links at both ends (the first node's previous link is NULL, and the last node's next link is NULL).
3. Circular Linked List: In a circular linked list, the last node points back to the first node instead of to NULL. Consequently, there are no NULL links in the structure.
4. None of These: This option implies that none of the other options qualify for not having NULL links.

Conclusion

Only the circular linked list does not have NULL links, as it creates a continuous loop.

Final Answer

c. Circular linked list
