7. Submit your solution to this form: [Google form](https://forms.gle/eDRGAJXpLqRxEExR6).
24+
25+
PS: You can commit and push as often as you like and GitHub Actions will re-evaluate your code every time.

You will need to look through the auto-grader logs (in the "Actions" tab) to see what exactly you got right or wrong.
