AVL Trees

AVL Trees. Neil Ghani University of Strathclyde. General Trees. Recall a tree is * A leaf storing an integer * A node storing a left subtree, an integer and a right subtree. We define algorithms by saying what they do to leaves and what they do to nodes.

Balanced Search Trees

Balanced Search Trees. BST: efficient lookup, insertion , deletion Average case: O(log n) for all operations since find is O(log n) [complexity of insert after find is O(1), why?] Worst case is bad, what's big-Oh? What's the tree shape?
