Cmput325 -- Legal Lisp Forms for Assignments

(Edited 4/Oct/04, for HW#2)
You may only use the following LISP functions and predicates

(car x)
(cdr x)
(cons x y)	

(atom x)
(null x)
(eq x y)
(equal x y)
(numberp x)
(listp x)

(eval y)
(funcall x ...)
(apply x y)

special forms (including logic connectives)

(defun ...)
(defmacro ...)
(let ((x y) (u v)...) z)
(let* ((x y) (u v) ...) z)
(lambda (x y) ...)

(quote x)        and its short form 'x
(function y)   as well as #
`( ...)         [added 21/Oct -- note gcl and clisp are slightly different here!]
(list a1 a2 ...)	
(if x y z)
(cond  ... ) 
(and x y ...)
(or x y ...)
(not x)

and numeric operators and comparisons such as

(+ x y)
(- x y)
(* x y)
(/ x y)
(< x y)
(mod x y)     [added 17/Oct]
(floor x)     [added 17/Oct]
(ceiling x)   [added 17/Oct]
(> x y)
(= x y)
(<= x y)
(>= x y)

You may also use a combination of car and cdr, such as

(cadr ...), (cdaar ...)

as well as

(first x)
(second x)
(third x)
...

(rest x)

etc.
