DSA in Python – Right Side View of Binary Tree | BFS + Reverse DFS | Leetcode 199 – Part 116 [Hindi]

🚀 Welcome to Part 116 of Code & Debug’s DSA Python Course!

In this video, we solve Leetcode 199: Binary Tree Right Side View using two elegant approaches:
1️⃣ BFS (Level Order Traversal) — capturing the last node of each level
2️⃣ Reverse DFS (Right → Left) — capturing the first node visited at each depth

📚 What you’ll learn in this video:
✅ What is the right side view and how it’s different from level order
✅ BFS approach using queue and level tracking
✅ DFS approach using reverse preorder traversal
✅ When to choose which method and why both are optimal
✅ Time and space complexity analysis of both solutions
