Worked Exercises from Picturing Programs

You don't learn much by typing a problem solution from the textbook into your computer, so I'm putting downloadable copies of the code for all the "Worked Exercises" in the textbook here.

• Spring 2010 edition of the book
• August 2010 (published) edition of the book
• August 2011 edition of the book, and DrRacket versions 5.1.1 and later (in which the picturing-programs library is bundled rather than being a separate download)
• The latest edition of the book, whatever that is
