Circular Linked List
Domain: Data Structures
🎯 Motivation
When the last node points back to the first, the list forms a circle. This is useful for round-robin scheduling and turn-based games.
📋 Concrete Example
A -> B -> C -> A (back to start). There is no null end. You keep cycling through the same nodes endlessly.
🔗 Analogy
A clock face. After 12 comes 1 again. There is no end to the hours — they cycle forever in a circle.
