I think I did it the complex way, lol. But.. mine could easily be modified to work for any rotation of rectangle and any length of sides and it should still work. So there's that.

std::cerr << "error message" << std::endl;

-edit-
Nevermind, solved.

I could not agree more. The description does not make any of these details clear.

I did more than stare at it. I printed out the example image and drew all over it, including tons of formulas and lines. I was in the middle of finding a really complex way at solving it when it hit me how simple it was.

Fixed, thanks!

It appears the issue has been fixed because I did not need to hack my code to get around any tests.

Edit: Unless you are talking about a different language than JS?

Thanks for your post!

Thank you for you solution ;-)

Congratulations ;-)

You didn't try to read the good discussion: the one I talked about has no spoiler flag activated (oops, I didn't see that there were several Davo36's messages actually... ;o) Search for the discussion where I say: "I have some troubles at the 11th test in the python version." -> the number of the test has changed in the meantime: my 11th is your 13th)

Hi,

You're wrong. ;) See the discussion I opened that is just above the one of Davo36: I ha d the same problem than you ;)

EDIT: BTW, what are the "c" charcters in your grids??
