A Survey on Binary Tree Codings
University of Tampere, Department of Computer Science, P.O. Box 607, SF-33101 Tampere, Finland
Several combinatorial and other programs deal with the structure (or the shape) of binary trees paying no attention to the data possibly maintained by the tree. For such programs it is useful to represent the structure without pointers and records. This paper surveys such representations. Especially, we concentrate on different ways of representing the structure of a binary tree by using a sequence of integers.
