## AVL Tree |

Description

AVL Tree implements a data structure container able to store/retrieve/delete a Key/Value relationship.

An AVL Tree is a self-balancing binary search tree. In an AVL Tree, the heights of the two child subtrees of any node differ by at most one; if at any time they differ by more than one, rebalancing is done to restore this property.

An AVL Tree containers has the following characteristics:

•AVL Self-Balanced Binary Tree

•one-to-one Key/Value relationship

•Values stored/retrieved/removed using unique lookup Key

•Keys must be unique

•no limit on Key length

•Value replaced if Key exist

•Tree always stays in Key order

•Tree may be traversed forward/backward in Key order

•Tree is self-balanced to maintain shortest average path to each Key

How to use in thinBasic

As a minimum, the following are the step required to use an an AVL Tree:

1.use Tree_New to create a new AVL Tree

2.use Tree_Set to add/change key/value pairs

3.use Tree_Get to retrieve key/value pairs

4.use Tree_Free to remove the entire AVL Tree and all associated key/value pairs
