4. (10 points) Create a visual representation of how the following program is stored in LISP (DEFUN equal_lists (lisl lis2) (COND ((ATOM 1isl) (EQ lisl lis2)) ((ATOM lis2) NIL) ( (equal_iists (CAR 1isl) (CAR 1is2)) (equal lists (CDR lisl) (CDR 1is2))) (T NIL)

Explanation / Answer

The following code in lisp defines a Lisp predicate function that take two lists as arguments and returns true if the two lists are equal, and NIL (false) otherwise.

(DEFUN equal_lists (lisl lis2) /. two list as argument

(COND ./ conditional

((ATOM lisl) (EQ lisl lis2))

((ATOM lis2) NIL)

( (equal_lists (CAR lisl) (CAR lis2))

(equal lists (CDR lisl) (CDR lis2)))

(T NIL) ./ return nill if not equal

)
