(define (deeprev l)           (if (null? l) '()               (if (list? (car l))                   (if (chek (car l)) (append (deeprev (cdr l)) (list (reverse (car l))))                            (append (deeprev (cdr l)) (list (deeprev (car l)))))                   (append (deeprev (cdr l)) (list (car l))))))
