Question 1.
What is the balance factor of a node with height 3 on the left and height 1 on the right?
Show hintHide hint
Remember balance factor = height of left - height of right.
Question 2.
What type of rotation is performed for a balance factor of +2?
Show hintHide hint
What action is taken to balance the tree?
3Question 3.
What is the resulting balance factor of a node where the left height is 4 and the right height is 2?
- -2
- 2
- 0
Show hintHide hint
Calculate using the difference of heights.
4Question 4.
True or False: The AVL tree guarantees that the tree remains perfectly balanced at all times.
- True
- False
Show hintHide hint
Consider what balance factors allow.
Question 5.
Given the sequence of integers 10, 20, 30, 40, 50, insert them into an AVL tree and show the necessary rotations.
Show hintHide hint
Draw the tree after each insertion.
Question 6.
After deleting a node from an AVL tree, describe how you would recheck the balance and what steps would follow for rebalance.
Show hintHide hint
Follow the rebalancing procedures you learned.
