What are some examples of circular linked lists?

Circular linked lists are data structures where the last node points back to the first node. Examples include: 1. A playlist where the last song loops back to the first. 2. A round-robin scheduling system in operating systems. 3. A multiplayer game where players take turns in a circular manner.

Can you explain how a circular linked list works?

Sure! In a circular linked list, each node contains a reference to the next node, and the last node points back to the first node, forming a circle. This allows for continuous traversal of the list without needing to reset to the head.

What are the advantages of using a circular linked list?

Some advantages include efficient memory usage, easy implementation of circular queues, and the ability to easily traverse the list in a loop without needing to check for the end.

Are there any disadvantages?

Yes, some disadvantages include the complexity of implementation, potential for infinite loops if not handled properly, and difficulty in finding the end of the list since it doesn't have a null terminator.
