LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - Longest ZigZag Path in a Binary Tree | LeetCode 1372 Explained Clearly in C++ (DFS Approach)

In this video, we solve LeetCode 1372 – Longest ZigZag Path in a Binary Tree using C++ and a clean DFS-based recursive approach. You’ll learn how to navigate left-right alternating paths efficiently and how to track path lengths with recursion. What you’ll learn: 🔹 How to apply DFS recursion on binary trees 🔹 How to handle alternating directions (left/right) elegantly 🔹 Clean and optimized C++ implementation Time complexity: O(n) Space complexity: O(h), where h = height of the tree 🎯 Perfect for those preparing for coding interviews and improving tree traversal logic.
