Welcome to srkcodes! In this Telugu coding tutorial, we solve Leetcode Question #102: Binary Tree Level Order Traversal — one of the most essential problems for understanding tree traversal techniques in DSA and coding interviews.

🌳 What’s covered in this video?
1️ ⃣ DFS Level-Order Traversal: Recursive depth-based approach explained step by step.
2️ ⃣ BFS Level-Order Traversal (Queue-Based): Simple and beginner-friendly iterative method.
3️ ⃣ BFS Level-Order Traversal (Two-List Level Tracking): Efficient technique to track nodes level by level.

👨 ‍💻 Whether you’re a beginner learning data structures in Telugu or an experienced coder preparing for interviews, this video gives you clear explanations and Python code for each approach. You’ll learn how to think recursively and iteratively when solving tree problems.

💡 Key Takeaways:
Understand the difference between BFS and DFS traversal.
Learn how queues and recursion work together in binary trees.
Strengthen your understanding of tree-level traversal logic.
