📄 Intuitive Description
Imagine you are exploring a family tree 🌳.
In Preorder Traversal, you always:
1️⃣ Visit the parent (Root) first 👑
2️⃣ Then go to the left child 👈
3️⃣ Finally move to the right child 👉
This is exactly what LeetCode 144 – Binary Tree Preorder Traversal asks us to do!
In this animated video, you’ll learn:
✨ How preorder works step by step
✨ Why recursion makes it easy to implement
✨ How to visualize the Root → Left → Right process on any tree
Whether you’re just starting with binary trees or preparing for a coding interview, this animation will make preorder traversal clear, visual, and easy to remember.
