Please hide prior-year CS 61 solutions

[huangyihe]

Dear GitHub user,

This is a notice from the CS 61 teaching staff at Harvard.

It appears that this public repository contains solutions to prior-year CS 61 programming problem sets. Since we reuse a subset of problem sets every year for this course, this opens up the possibility of plagiarism by current students by looking at prior-year solutions. Please note that it is against the course policy to publicly post solutions to problem sets or exams without permission at any time, including after you have finished the course.

We hereby request that you remove public access to this repository from GitHub and other similar services. If you do not wish to pay for GitHub to make these repositories private, you can host private repositories for free on services like Bitbucket or GitLab. If you are a current Harvard student, you can get GitHub education credit to enable free private repositories or use Harvard's institutional version of GitHub.

We apologize for any inconvenience and we appreciate your cooperation.

Best regards,
Harvard CS 61 Team
