Leetcode - 104. Maximum Depth of Binary Tree

Finding the maximum depth (or height) of a binary tree is one of the most classic problems in tree data structures. In this post, we’ll explore three powerful approaches: ✅ Recursive DFS ✅ Iterative BFS (Level Order) ✅ Iterative DFS (Preorder with Stack) 1️⃣ Recursive DFS
