Exercise 5.11: Write a procedure make-verifier that takes f and m as arguments and returns a procedure that verifies a number accordingly.
Example:
(define check-isbn (make-verifier * 11))
(check-isbn 0262010771) ⇒ #t
Here is the form:
(define make-verifier
(lambda (f m)
;; Return a procedure that takes an
;; integer and tests if it is valid
))
If written correctly, make-verifier can create other verifiers
depending on f and m.
