Observe that our model of evaluation allows for combinations whose operators are compound expressions.
(a) Use this observation to describe the behavior of the following procedure:
(define (a-or-b-depending-on-value a b) ((cond ((< b a) +) ((= b 0) -) ((= a 0) /) (else *)) a b))
Your answer should describe what happens for all integer values of a and b. Illustrate your answer using the substitution model assuming applicative order evaluation.
(b) Write a procedure (check-it op p q r) that returns #t if p op q = r and #f otherwise. For example, (check-it * 3 2 6) would return #t as 3 * 2 = 6.
