🚀 Welcome to Part 83 of Code & Debug’s DSA in Python Course!
In this lecture, we implement the Queue Data Structure using Arrays from scratch. Queues follow the FIFO (First-In-First-Out) principle and are widely used in OS scheduling, caching, and level order traversals.
📚 What you’ll learn in this video:
✅ What is a Queue and real-life examples of its usage
✅ Step-by-step implementation of a queue using arrays
✅ Operations: enqueue(), dequeue(), front(), rear(), isEmpty(), isFull()
✅ Circular queue concept and how to prevent overflow
✅ Time and space complexity analysis of all operations
💡 Why is this important?
Understanding queue fundamentals and implementation logic is essential for solving problems in trees, graphs, OS simulation, and multi-threading scenarios. Manual implementation helps strengthen your core DSA skills.
