DSA in Python – Level Order Traversal (BFS) in Binary Tree | Using Deque | Part 109 [Hindi]

🚀 Welcome to Part 109 of Code & Debug’s DSA in Python Course!

In this video, we cover Breadth First Search (BFS) for Binary Trees, also known as Level Order Traversal. You’ll learn how to implement it efficiently using deque and a for loop to process nodes level by level.

📚 What you’ll learn in this video:
✅ What is BFS / Level Order Traversal and where it’s used
✅ How to use deque from collections for efficient queue operations
✅ For loop structure to track each level separately
✅ Step-by-step Python implementation with dry run
✅ Time and space complexity analysis
