COWondering how to traverse a binary tree? 🌳
Here’s a simple breakdown of each technique:
1️⃣ Inorder Traversal:
- Visit the left subtree
- Visit the node
- Visit the right subtree
- Useful for getting nodes in non-decreasing order.
2️⃣ Preorder Traversal:
- Visit the node
- Visit the left subtree
- Visit the right subtree
- Great for creating a copy of the tree.
3️⃣ Postorder Traversal:
- Visit the left subtree
- Visit the right subtree
- Visit the node
- Used mostly for deleting or freeing nodes and space of the tree.
