Queues: Managing Sequential Data Flow

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:

  1. Simple Queue: Basic FIFO structure.
  2. Circular Queue: The rear of the queue connects to the front, optimizing space.
  3. Priority Queue: Elements are dequeued based on priority, not order.
  4. 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.
