Problem Set 3

What to Do

  1. Log into using your GitHub account
  2. Run update50 in your codespace’s terminal window to ensure your codespace is up-to-date and, when prompted, click Rebuild now
  3. Submit Plurality
  4. Submit one of:
    • Runoff, if feeling less comfortable
    • Tideman, if feeling more comfortable

If you submit both Runoff and Tideman, we’ll record the higher of your two scores.

When to Do It

By the College Board’s AP deadlines for the 2023–2024 academic year.


  • Try out any of David’s programs from class via Week 3’s sandboxes.
  • If you see any errors when compiling your code with make, focus first on fixing the very first error you see, scrolling up as needed. If unsure what it means, try asking help50 for help. For instance, if trying to compile plurality, and
    make plurality

    is yielding errors, try running

    help50 make plurality
