Hw03 feedback

Hey,

TL;DR the code is OK, you don't need to fix anything. I have prepared some comments on how to make your code look more neat in the Changes section, so I would really appreciate if you could find some time to go through them.

If you have any questions regarding the feedback, feel free to ask me in the comment section. Otherwise, feel free to close the MR.

Best regards,

Rado
