Linked List Structure - Circular List

Circular Linked List

A circular linked list replaces the final null with a tail-to-head link, so traversal can continue around the ring.

No Null Tail

The last node points back to head instead of ending at null.

Algorithms must stop after returning to the start node.

Keeping a tail pointer makes insertion after tail efficient.

Round-robin scheduling and repeated cycles naturally match circular lists.
