SIMPLY SCHEME EXERCISES
NOTE: It would be cool to see other peoples solutions to these problems! ;)
This project contains my solutions to the exercises and projects presented at the end of each chapter in the textbook Simply Scheme (Brian Harvey and Matthew Wright, 2nd ed, MIT 1999).
The book is freely available here: http://www.cs.berkeley.edu/~bh/ss-toc2.html
I have omitted the first two chapters as they are very basic and contain little or no actual code. Also, on most chapters, there is a section called "Boring exercises" and a section called "Real exercises". I've omitted all boring exercises because their solutions contain no actual code and they are... well... boring.
The code samples throughout the book use a slightly modified implementation of Scheme (syntactically LISP, but with some additional primitive procedures). To get this augmentation working correctly in Dr. Scheme, you must choose "Pretty Big" from the languages menu and then install the extensions via the REPL:
> (require (planet dyoo/simply-scheme:1:2/simply-scheme))
I try to only use concepts and procedures that have been introduced when answering questions (e.g I don't use recursion before it's been discussed, nor do I use variables -- other than the lambda shorthand notation -- until chapter 7).
For the record, I recommend this particular book for anyone who:
- Wants to (re)learn LISP and/or functional programming
- Finds SiCP difficult to digest (hint: read SS and then SiCP)
- Is looking for a good introduction to programming
