Challenge Problems
Push your limits with advanced challenges
You are given an unbalanced binary tree where a node has a height of +3. Describe the steps to rebalance this tree using rotations.
💡 Hint: 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.
💡 Hint: Think about how the insertion affects the tree balance and the corresponding rebalancing operations after every insertion.
