I think there is an issue with the Crystal/Ruby version :
Test.assert_equals(next_day_of_week(7,3),6)Why is the answer 6 ? 3 is reprsented in binary as the following0000011The 5ths bit is not a positive bit ... the answer should be 1 ... Or is there something I'm missing ?Surely, it's a wrong result. Two translations from @GiacomoSorbi. Let me try to fix it ;-)
Ruby fixed. Please help me re-test it.
Test cases seems good, thank you :) The sample tests cases are still wrong though ;)
I've fixed it, but you can not see the changes until you solve it and train again.
Crystal was fixed now. Please test ;-)
Seems all good, thank you
Many thanks for your help ;-)
Just out of curiosity: why doesn't the week start with monday?
All I know is that most calendars are in this order. But I don't know why too.
Interesting. I don't recall ever seeing such a calendar. The ones I have around all start on monday and the one on this operating system, too. Maybe it's an American thing. They also use outdated European units of measure and a weird date format, that puts the day in the middle.
China's calendar also start from sunday. I don't know Japan's calendar ;-)
https://en.wikipedia.org/wiki/Sunday
It was common at a time in Europe, too, but it was upgraded (ISO 8601).
Contrary to what my name and some of my kata would suggest, I'm not Japanese. Though, now that you mention it, Japanese calendars also start with Sunday.
Ruby and Crystal, cheers :)
Done. Thanks ;-)
