A list of the squares
The procedure square-list takes a list of numbers as argument and returns a list of the squares of those numbers.
(square-list (list 1 2 3 4)) (1 4 9 16)
Here are two different definitions of square-list. Complete both of them by filling in the missing expressions:
(define (square-list items) (if (null? items) nil (cons <??> <??>))) (define (square-list items) (map <??> <??>))
