Hopefully you guys can assist me. I was given these few questions and I have no clue where to start. So if anyone could answer them they would be of much help. Thanks. Consider the following functions: (define get-evens (lambda (lst) (cond ((null? lst) '()) ((even? (car lst)) (cons (car lst) (get-evens (cdr lst)))) (else (get-evens (cdr lst)))))) (define get-odds (lambda (lst) (cond ((null? lst) '()) ((odd? (car lst)) (cons (car lst) (get-odds (cdr lst)))) (else (get-odds (cdr lst)))))) (define get>2 (lambda (lst) (cond ((null? lst) '()) ((> (car lst) 2) (cons (car lst) (get>2 (cdr lst)))) (else (get>2 (cdr lst)))))) 1. Write another function that accepts a test as one of its arguments, and which can then behave like each of the above functions. Starting with: (define extract (lambda (test? lst) 2. Use extract to define get-evens, get-odds, and get>2 </td></tr></tbody></table> _________________________________________________ For list-related administrative tasks: <a href="http://list.cs.brown.edu/mailman/listinfo/plt-scheme" target="_blank">http://list.cs.brown.edu/mailman/listinfo/plt-scheme</a> </blockquote></div>
