How many “good” nodes does your binary tree have? In this video, we solve LeetCode 1448 – Count Good Nodes in Binary Tree step by step in C++, using DFS traversal and recursion. You’ll learn how to count nodes that are not smaller than any value along the path from the root — a great problem to deepen your understanding of binary tree logic. 💡 You’ll discover: ✅ What defines a “good” node in a binary tree ✅ How to use recursion and backtracking to keep track of maximum values ✅ A clean, efficient DFS-based C++ implementation 🎯 Perfect for practicing depth-first search (DFS), recursion, and tree traversal techniques. 📘 More Binary Tree problems: Binary Trees Demystified Playlist #LeetCode #Cplusplus #BinaryTree #DFS #Algorithms #Programming #CodingInterview #LANAcademy @reper #foryou #viral #reper #urmaritori #for
