AVL Tree

After reading this chapter and engaging in the embedded activities and reflections, you should be able to:

• Elaborate on the purpose of structural rotation.
• Describe, trace and implement structural rotations: single right, single left, double right-left, double left-right.
• Explain and trace the balancing operations of an AVL tree.
• Select the appropriate rotation type in order to rebalance an AVL tree after an insertion/removal operation is performed.
• Implement the core operations of OrderedMap efficiently with an AVL tree.
• Analyze the time/space efficiency of an AVL tree.
