Class 41: Deep Recursion

Back to Pairs and Pair Structures. On to Association Lists and Searching.

This outline is also available in PDF.

Held: Tuesday, 15 April 2008

Summary: We begin our exploration of non-list structures that one can build with pairs (aka cons cells). In particular, we consider a recursive data structure typically called a tree. We then explore how one writes recursive procedures that work with trees.
