Lisp function call error

Question

I\'ve written a Lisp function like this:

(defun power (base exponent)
  (if (= exponent 0)
      1
    (* base (power (- exponent 1)))))

Wh

Answer 1

The recursive call is your problem. You forgot to pass the base in as the first argument.

(* base (power (- exponent 1)))))

should be:

(* base (power base (- exponent 1)))))
