Class 23: Recursion Basics

Back to Iterating Over Positions. On to Recursion Basics, Continued.

This outline is also available in PDF.

Held: Friday, 29 February 2008

Summary: We begin our exploration of recursion, the most general form of repetition available in Scheme. You can use recursion to both build and iterate over different kinds of values. Today, we explore how you use recursion to build simple numeric values from lists, and how to remove elements from lists.
