[Announcement] Test cases for the past assignments

[goodtaeeun]

Hi all.
After each assignment, we will push the test cases to your repository.
If you have failed to pass some, you may try to improve your implementation furthermore.

In order to identify your homework repository, we need your GitHub ID.
If you have not responded to the past survey on GitHub IDs (#155 ), please do so.
Otherwise, we won't be able to provide test cases for you.
