Detailed information on the tasks can be found on the course page (Moodle).
The point of the automated tests is to ensure that your submissions are fast enough, and to help with debugging. The tests are not intended to counteract cheating. (that is what the spot checks are for.)
In practice:
- Do not write you code in a way where you circumvent checks in specific tests
- Do not submit solutions that are not correct in principle but happen to pass tests (e.g. because you are lucky)
- Do not submit someone else's work as your own
If you do want to try submitting suspicious stuff, please create a separate account for doing so.
Mistakes happen. If you brake the rules, please let the teacher know, so that the issue can be resolved amicably.
