In this video, we solve Count Good Nodes in Binary Tree (LeetCode 1448) using Swift. I show how to track the maximum value along a path while traversing a binary tree with DFS.
This medium-difficulty problem teaches valuable lessons about state tracking during tree traversal, a common pattern in technical interviews.
📌 What You'll Learn:

Maintaining state during tree traversal
Using tuples in Swift to carry multiple pieces of information
How to track maximum values along specific paths
Converting recursive solutions to iterative approaches
Techniques for optimizing tree traversal algorithms
