For user-friendliness, it is better not to use trailing spaces in data input or output. Use it at the front has less problem.

Someone might print the puzzle and I/O data on paper to share. Your invisible tails will cause disappointment.

Is it possible to correct this or it’s too late ?

You can always change your contribution by going into Community > Contributions > “My contributions” and then select it, and then “edit”

But I would consider Not changing it. I think it’s fine the way it is.
Since there can be only one “right answer” I think displaying it as a full square is what makes most sense.

Okay thanks for your answer :slight_smile:

Don’t change it, just warn that there are trailing spaces.

Agree on not changing after it has been solved by many.
Recommendation for future puzzles: use a . instead of space in similar output requirements. It is more appropriate then asking for a trim, yet still readable.

I already warn to don’t delete trailing spaces in output section

Thanks for the advice, I’ll think about that next time

Warn that there are trailing space, not to not delete them, because trailing spaces are not mentionned before.

For curious people, i show there the biggest ouput allowed in standard output by Codingame (n=44).
If n>=45 there will be deleted lines and […] in the output.
Enjoy :slight_smile:
