Problem Set 9

Collaboration on problem sets is not permitted except to the extent that you may ask classmates and others for help so long as that help does not reduce to another doing your work for you, per the course’s policy on academic honesty.

The staff conducts random audits of submissions to CS50x. Students found to be in violation of this policy will be removed from the course. Students who have already completed CS50x, if found to be in violation, will have their CS50 Certificate permanently revoked.

GitHub now requires that you use SSH or a personal access token instead of a password to log in, but you can still use check50 and submit50! See cs50.ly/github for instructions if you haven’t already!

Be sure you have completed Lab 9 before beginning this problem set.
