    • Submitting your Assignment
    Please submit this assignment in a single Definitions Pane and a single Interactions Pane through Moodle. Points will be deducted for completing the assignment with multiple Definitions and/or Interactions Panes.

    Be sure to include your first and last name as a comment in the first line of both the Definitions Pane and the Interactions Pane.

    The file name for the Definitions Pane needs to be "hw6[LastName]Def.rkt" where:
  • [LastName] is replaced with your last name.
  • For example, if I were submitting this assignment, I would name the file "hw6WittensteinDef.rkt".

    Similarly, the file name for the Interactions Pane needs to be "hw6[LastName]Int.rkt".

    Please let me know if this is not clear or if you are unsure exactly what filename to use. Part of your grade is using the correct filenames.
