Q1: Over or Under
Define a procedure over-or-under which takes in a number x and a number y and returns the following:
- -1 if x is less than y
- 0 if x is equal to y
- 1 if x is greater than y
*Hint: You can use cond
(define (over-or-under x y) 'YOUR-CODE-HERE
)
;;; Tests (over-or-under 1 2) ; expect -1 (over-or-under 2 1) ; expect 1 (over-or-under 1 1) ; expect 0

Q2: Filter
Write a procedure filter-lst, which takes a predicate f and a list lst, and returns a new list containing only elements of the list that satisfy the predicate. The output should contain the elements in the same order that they appeared in the original list.
(define (filter-lst f lst)
'YOUR-CODE-HERE
)
;;; Tests (define (even? x) (= (modulo x 2) 0)) (filter-lst even? '(0 1 1 2 3 5 8)) ; expect (0 2 8) |
