AVL Trees

AVL Trees. Joe Meehean. Problem. BST efficiency relies on height lookup, insert, delete: O(height) a balanced tree has the smallest height We can balance an unbalanced tree DSW expensive How can we ensure that our BST stays balanced? after inserts and deletes. AVL Trees.

Binary Search Trees

Binary Search Trees. If we want to perform a large number of searches in a particular list of items, it can be worthwhile to arrange these items in a binary search tree to facilitate the subsequent searches.

AVL Tree Rotations

AVL Tree Rotations. About Rotations. A right rotation can be done on any node having a left child. A left rotation can be done on any node having a right child. A rotation always preserves the BST invariants. It might or might not decrease the height of the subtree. Parent. Parent.
