Haskell for Beginners

This is a collection of homework problems created to teach the Haskell for Beginners class at The Hacklab @ North Boynton. The problems follow the text for the class, Learn You a Haskell for Great Good!, chapter by chapter. Each problem file has problems intended to exercise the knowledge learned in just one section heading of the chapter that it is in. The chapter numbers given below follow those for the online text. If you are using the physical text, the chapter numbers in the book lag behind by one until you get to chapter 10. Chapters 8 and 9 in the together cover the the context of chapter 9 online.

In addition there is a small midterm project to be completed after Chapter 8.
