Wormholes of Cygnus
Back to General discussions forum
Hmmm... I know three people solved this already, but I get the error message like:
Expected: 65
...which feels off, since the answer should be two numbers. Any advice?
...and the second time my answer was accepted. Maybe I had a trailing space...?
Vladimir, Hi!
If you have just the message you have shown, with single value instead of two - I suspect it is really some subtle bug on our side! I'll try to reproduce this... Sorry for inconveinence and thanks for reporting it!
As for trailing spaces - peeking into the code I see here is trim($answer) so trailing and leading spaces shouldn't
harm.
Unrelated to the issue, but for the German-speaking folks out there: Das Haus vom Nikolaus.
Hopefully the issue is fixed. Supposedly it was caused by the unexpected fact that range(a, b) function in PHP
returns b inclusive, unlike in Python. Probably Kevin was unaware of this fact - while I myself was unaware of existence
of such function altogether :))) Thus today we both learnt something new.
To Mathias: I pretty well remember we were drawing such "Häuser" in childhood, though I never know they are associated with Nikolaus!
Moreover I learnt about Nikolaustag just couple months ago - trying to read some kids book in Polish - before that I thought that Nikolaus brings gifts on Chritmas itself in western traditions :o
