If the slope of a tree is -1, what does it indicate?
💡 Hint: Think about the definition of slope related to height.
True or False: A slope of -1 requires at least one rotation to restore balance.
💡 Hint: Consider the conditions under which rebalancing is required.

Challenge Problems
Push your limits with advanced challenges
You have a binary search tree where multiple insertions have caused a slope of -1. Show the steps you would take to rebalance it through rotations.
💡 Hint: Remember the conditions for each type of rotation.
If you delete a node from an AVL tree that causes an imbalance leading to a slope -1, explain how you would restore balance through rotations.
💡 Hint: Make sure you check slopes at the affected nodes after adjustments.
