Program: The fac function. This is the classical recursive edition of fac.
| | ;; Calculate the factorial of n.
;; .parameter n An integer
;; .pre-condition The integer must be non-negative.

(define (fac n)
(if (= 0 n) 1 (* n (fac (- n 1))))) |

Program: The fib function. This is the classical recursive edition of fib, which is very time consuming.
| | (define (fib n)
(cond ((or (= n 0) (= n 1)) 1)
(else (+ (fib (- n 1)) (fib (- n 2)))))) |
