Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the balance factor in AVL trees?
💡 Hint: It's related to the heights of current node's children.
Question 2
Easy

Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What does a balance factor of -2 indicate?
- The left subtree is heavier
- The right subtree is heavier
- The tree is balanced
💡 Hint: Think about how height differences affect balance.
Question 2
When is a left rotation performed?
- True
- False
💡 Hint: Recall when imbalance necessitates rotative adjustments.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
