public class ShortBTNode
extends java.lang.Object
ShortBTNode
provides a node for a binary tree. Each node
contains a piece of data (which is a reference to an object) and references
to a left and right child. The references to children may be null to indicate
that there is no child. The reference stored in a node can also be null.
Limitations:
Beyond Int.MAX_VALUE
elements, treeSize
, is
wrong.
