Please review :)

The code worked in my test and the output matches the assignment requirements.
I especially like that the code is clearly structured and easy to follow. I also really liked the “Algorithm Steps” section in the README, because it makes the overall program flow very easy to understand.

One small improvement could be to make the README examples a bit more concrete by showing one or two actual expected outputs directly there as well.

One question or edge case to consider: what should happen if -d is used on an input file that does not actually contain a diagonal block?

++ Top-tier error message game!! :)

Thank you Anes,
I got Inspired by your error messages from the last time :)

I reviewed my code and README after your suggestions. The -d flag handling was a good point. I didn't thought about it because my code didn't throw an error at this point.

Thank you :)
