Challenge Problems
Push your limits with advanced challenges
Given a series of values to insert into an AVL tree, demonstrate the rebalancing steps needed to maintain balance. List the rotations performed after each insertion.
💡 Hint: Refer to individual balance factors after each node is added to check for required rotations.
Create a visual representation of an AVL tree before and after a series of rotations. What does this tell about the efficiency of AVL balancing relative to normal BSTs?
💡 Hint: Be attentive to height imbalances when comparing the two tree types.
