I'm trying to teach myself scheme (racket) and decided to try writing
fizzbuzz. My program mostly works, but instead of getting a single list, I
get a list with a dot before the last list item, which I assume means I've
got a 'cons' at the end rather than just one list. What am I doing wrong?
Any general comments on style or approach also welcome.
Thanks,
Leonard
#lang racket
(define (printer num)
(cond((and (= 0 (remainder num 3)) (= 0 (remainder num 5))) 'fizzbuzz)
((= 0 (remainder num 3)) 'fizz)
((= 0 (remainder num 5)) 'buzz)
(else num)))
(define (fizzbuzz limit)
(define (helper current limit)
(cond ((>= current limit) (printer limit))
(else (cons (printer current)
(helper (+ 1 current) limit)))))
(helper 1 limit))
(fizzbuzz 10)
'(1 2 fizz 4 buzz fizz 7 8 fizz . buzz)
