Challenge Problems
Push your limits with challenges.
Question 1
Given a series of insertions into an AVL tree, illustrate the tree after each insertion and indicate any necessary rotations. Start with an empty tree and insert the values: 10, 20, 30, 25, 22.
💡 Hint: Keep track of the slopes after each insertion.
Question 2
You have a balanced AVL tree. Describe the steps you would take to delete a node that causes an imbalance, ensuring to maintain the AVL property afterward.
💡 Hint: Consider the case of a node deletion affecting the height balance throughout the tree.
