Your code is 100% correct, conceptually. Sadly, it’s suffering from a mistake that I saw many many times in the 90s and before. And that’s precisely why we get beginners started on Beginning Student Language in DrRacket instead of plain Racket. Try it out for your next few exercises or even this one, to see whether the error message would have helped. — Matthias -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
