Hi! I was wondering if you could help me with the following LISP programming question:

Use do to define (minimum lst) which returns the minimum of a list of numbers. You may want to define an auxiliary function (smaller x y), using if, which returns the smaller of two numbers.

So far I have this:

(defun smaller (x y)

"(x y) Returns the smaller of two numbers."

(if (< x y) x y))

(defun minimum (lst)

"(lst) Returns the minimum of a list of numbers."

(do ((numbers lst (cdr numbers))

(min 0))

((smaller min (car lst))

But I'm not sure how to finish the second function in LISP...
