4 cards from this section. Quick, good the night before a test.
What indicates a height imbalance of +2 at a node?
Think about the heights of both subtrees.
What is a rotation in the context of binary trees?
Consider what happens to the structure of the tree during rotation.
What does a height of +2 in a binary tree node indicate?
Think about what balance means for each subtree.
True or False: A single rotation can fix any height imbalance.
Consider the complexity of imbalances.
You are given an unbalanced binary tree where a node has a height of +3. Describe the steps to rebalance this tree using rotations.
Consider the roles every node plays in a binary tree.
Design an algorithm in pseudo-code for inserting a node into an AVL tree while ensuring rebalancing through rotations.
Think about how the insertion affects the tree balance and the corresponding rebalancing operations after every insertion.
