- Written in C using OOP techniques, these modules provide three forms of
- binary tree: Simple (unbalanced) AVL (height-balanced), and Splay. AVL
- trees are re-balanced after every insertion or deletion. For each node in
- the tree, the difference in height between the left and right subtree is
- at most 1. Splay trees use a different approach. Each time a node is
- accessed (inserted, deleted, or directly found via a search), the node is
- bubbled to the top of the tree. This has the effect of making the tree
- 'bushier' and placing the most frequently accessed nodes nearer to the
- top.
-
- The functions are non-recursive to limit stack space usage, and can also
- be made into a run-time library. The type of tree used is determined by
- which header file is included with your program. No other code changes
- are necessary.
-
- Pretty darn fast, too, IMHO.
