A circular queue can be implemented using array and linked list. To implement a circular queue using a linked list, you must use a circular linked list where the rear node is connected to the front node.
Time Complexity Analysis
- Time Complexity
- Enqueue : \(O(1)\)
- Dequeue: \(O(1)\)
- Space Complexity : \(O(n)\) as the queue is size of \(n\)
