Hey Everyone!
What Are Queues?
Queues operate on the principle of First In, First Out (FIFO). Imagine standing in line at a coffee shop: the first person in line is served first.
Core Operations:
- Enqueue: Add an element to the end of the queue.
- Dequeue: Remove an element from the front of the queue.
Types of Queues:
- Simple Queue: Basic FIFO structure.
- Circular Queue: The rear of the queue connects to the front, optimizing space.
- Priority Queue: Elements are dequeued based on priority, not order.
- Deque (Double-Ended Queue): Elements can be added or removed from both ends.
Applications of Queues:
- Task Scheduling: Operating systems use queues to manage processes.
- Data Buffering: Queues manage streaming data in video playback or networking.
- Breadth-First Search (BFS): A graph traversal algorithm that uses queues.
