|

* This file defines data structures for different types of trees:
|
||||
* splay trees and red-black trees.
|
||||
*
|
||||
* A splay tree is a self-organizing data structure. Every operation
|
||||
* on the tree causes a splay to happen. The splay moves the requested
|
||||
* node to the root of the tree and partly rebalances it.
|
||||
*
|
||||
* This has the benefit that request locality causes faster lookups as
|
||||
* the requested nodes move to the top of the tree. On the other hand,
|
||||
* every lookup causes memory writes.
|
||||
*
|
||||
* The Balance Theorem bounds the total access time for m operations
|
||||
* and n inserts on an initially empty tree as O((m + n)lg n). The
|
||||
* amortized cost for a sequence of m accesses to a splay tree is O(lg n);
|
||||
*
|
||||
* A red-black tree is a binary search tree with the node color as an
|
||||
* extra attribute. It fulfills a set of conditions:
|
||||
* - every search path from the root to a leaf consists of the
|
||||
* same number of black nodes,
|
||||
* - each red node (except for the root) has a black parent,
|
||||
* - each leaf node is black.
|
||||
*
|
||||
* Every operation on a red-black tree is bounded as O(lg n).
|
||||
* The maximum height of a red-black tree is 2lg (n+1).
