1. Consider the following Scheme function:

(define (f n x y z)
(if (> n 0)(and
(f (- n 1) x z y)
(display (cons n(cons x (cons y ‘()))))
(f (- n 1) z y x))))

The return value of the call: (f 3 ‘a ‘c ‘b)

is:

(3 a c)(2 a b)(1 c b)(3 a c)(1 b a)(2 b c)(1 a c)

Question 7 options:True

False

2. Consider the following Scheme function:

(define (f n)
(if (= (/ n 2) 0)
#t
#f))

Which is the right answer for the call: (f 5)

Question 10 options:

5

2

#f

#t

3. Suppose the content of the variable: lst is a list:

(1 2 3 4 5 6).
In the functional programming Scheme, we can replace:
(caddr lst)
by:

Question 11 options:

(car (cdr (cdr lst)))

(cdddr lst)

(caaar lst)

(cdadr lst)
