DSA Python – Binary Tree Maximum Path Sum | Optimized DFS Approach | Leetcode 124 – Part 113 [Hindi]

🚀 Welcome to Part 113 of Code & Debug’s DSA in Python Course!

In this lecture, we solve the Leetcode 124: Binary Tree Maximum Path Sum problem using an efficient DFS-based approach. We compute the maximum path sum by considering every possible path that can pass through a node — including both its left and right subtrees.

📚 What you’ll learn in this video:
✅ Understanding what a path means in a binary tree
✅ How to handle negative path sums while traversing
✅ Optimized postorder DFS with global maxi tracker
✅ Step-by-step dry run with clear logic
✅ Time and space complexity breakdown
