Identification of Linked List Types

In computer science, a linked list is a data structure used for storing a sequence of elements. Each of these elements contains a reference (or link) to the next element in the sequence. Here, we’ll go through the options provided:

1. Linear linked list: This is a basic type of linked list where each node points to the next node and the last node points to null. This is a valid type of linked list.

2. Doubly linked list: In this type of linked list, each node contains two links: one to the next node and one to the previous node. This is also a valid type of linked list.

3. Circular linked list: This type of linked list forms a circle, meaning the last node points back to the first node instead of null. This is a valid type of linked list as well.

4. Singly linked list: This type is similar to a linear linked list, where each node contains a link to the next node only. This is indeed a valid linked list as well.

Conclusion

All the options listed (a, b, c, d) are types of linked lists. However, since the question specifically asks for the option that is NOT a type, if we interpret that literally, technically all options given do exist as forms of linked lists.

However, if one were to consider the term "Linear linked list" as a broader category that incorporates the other types, it might be less recognized as a standalone distinct type.

Final Answer

The answer is a. Linear linked list, as it can be seen as a broader term encompassing other types rather than a distinct type itself.
