Dear students,

I have recorded four short additional videos to go through several worked examples on BST global and local rebalancing , as well as AVL insertion and deletion .

The videos cover:

1. Example 1: Global rebalancing
2. Example 2: Global rebalancing
3. Example 3: Local rebalancing and root insertion
4. Example 4: AVL insertion and deletion

If you did not attend the lecture or have not yet watched the recording, please watch the lecture video first, then these example videos. They are intended to help you better understand the concepts through step-by-step examples.

The OneNote solutions are also available here .

See you tomorrow.

Best regards,
Tahereh
