Ever flipped a mirror image? That’s exactly what you’re doing here but with data.
Inverting a binary tree means swapping the left and right child nodes at every level. A simple idea, but deeply rooted in recursion. This is one of those elegant problems that reveals the power of thinking recursively.
𝐈𝐧 𝐭𝐡𝐢𝐬 𝐯𝐢𝐝𝐞𝐨:
♦Visual walk-through of how each node is flipped
♦Pseudo-code using recursion
♦Dry run with detailed tree transformations
♦Time and space complexity explained simply

WOAn AVL tree is a self-balancing binary search tree in which the heights of the left and right subtrees of any node differ by at most one, known as the balance factor. The balance factor is calculated as the height of the right subtree minus the height of the left subtree. It ensures efficient operations such as insertion, deletion, and search by automatically adjusting its structure to maintain balance based on the balance factors of its nodes (if the balance factor is more than. 1 or less than -1). The adjustment happens via rotation (left, right, left-right, right-left).
For better understanding of Balance factor (the numbers above nodes) and rotations, - pause the video and rewatch.

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.

Step 1: Identify the Node to Delete
Find the node that you need to delete in the BST.
Step 2: Check Cases
There are three cases when deleting a node:
Node has no children (Leaf Node) → Simply remove the node.
Node has one child → Replace the node with its only child.
Node has two children → Find the inorder successor (smallest node in the right subtree), replace the node’s value with it, and then delete the successor.
Step 3: Adjust Pointers
Modify the parent node’s pointer to maintain the BST structure.
Step 4: Return the Updated BST
Ensure the tree remains a valid BST after deletion.
Time Complexity
O(log N) for a balanced BST
O(N) in the worst case (skewed tree)
