Challenge Problems
Push your limits with advanced challenges
Given an AVL tree that has become unbalanced after several insertions, describe the process of identifying which rotations to perform to restore balance.
💡 Hint: Evaluate the height differences carefully to make an informed decision.
Construct an AVL tree by inserting the following sequence of numbers: 30, 20, 40, 10, 25, 22. Illustrate each step including any necessary rotations.
💡 Hint: Keep track of height after each insertion to visualize balance.
