Simply store the files in your turnin SVN repository to submit this program as you did for Assignments 1 and 2.   In contrast to Assignments 1 and 2 where you could put the programs for all problems in the single file (HW01.rkt for Assignment 1 and HW02.rkt for Assignment 2), you must store the solution to each problem in a separate .rkt file: HW04-1.rkt, HW04-2.rkt, HW04-3.rkt, and HW04-4.rkt (if you do the extra credit problem). Unfortunately, none of the languages supported by DrRacket will allow these files to be combined.

All of the student languages—the only ones that support check-expect—prohibit redefinition.
