If a binary search tree is balanced, it allows for very efficient searching. As with the binary search, it takes O(lgn) steps to find an element in a balanced binary search tree. But without further restrictions, a binary search tree may grow to be very unbalanced. The worst case is when the elements are inserted in sorted order. In that case the tree degrades to a linear list, thereby making the search algorithm an O(n) sequential search. EXAMPLE 12.6 An Unbalanced Binary Search Tree

This is the same input data as in Example 12.5, but in a different order: 99, 22, 88, 33, 77, 55, 44. The resulting binary search tree is shown in Figure 12.10 on page 236. This shows that the same input in different order produces a different tree. But more important, it shows that it is not unlikely for the binary search tree to be linear, or nearly linear.

PERFORMANCE OF BINARY SEARCH TREES Both the insert() and the search() functions begin at the root of the tree and proceed down toward the leaves, making one comparison at each level of the tree. Therefore the time required to execute either algorithm is proportional to h + 1, where h is the height of the tree. The search() function may terminate before reaching a leaf, but h + 1 is still an upper bound on the number of comparisons that it can make. Theorem 12.2 In a binary search tree of size n, the insert() and the search() functions each require O(lgn) comparisons in the best case. In the best case, the binary tree is completely balanced and nearly full, so by Corollary 11.2 on page 202, h = lg(n+1) 1 = O(lgn). Theorem 12.3 In a binary search tree of size n, the insert() and the search() functions each require O(n) comparisons in the worst case. In the worst case the tree is linear, so h + 1 = n = O(n).

AVL TREES
SEARCH TREES
The imbalance problem illustrated in Example 12.6 can be avoided by imposing balance constraints on the nodes of the binary search tree. Define the balance number at any node of a tree to be the difference between the height of its left subtree and the height of its right subtree. An AVL tree is a binary search tree where the balance number at each node is either 1, 0, or 1. The name comes from the two inventors of this method: G.M. Adel son-Velskii and Y.M. Landis. The tree in Figure 12.12 is not an AVL tree because it is imbalanced at node C. Its balance number there is 2, which is outside the allowable range. It is also imbalanced at node G. The tree in Figure 12.11 is an AVL tree: Every balance number is either 1, 0 or 1. EXAMPLE 12.7 An AVLTree CLASS
