My code is here:)
;3.) A function called allDiff? that takes as parameters two lists. The
function returns #t if none of the elements in the first list can be found in
the second
(
define (allDiff? list1 list2)
( if (null? list1) '()
( if (null? (cdr list1))
(if (memq (car list1) list2) #f #t)
(if (memq (car list1) list2) #f
(allDiff? (cdr list1) list2))
)
)
)
See this error. Please Help
list1: undefined;
cannot reference an identifier before its definition
