In java version of kata the method name is starts with big L.
This goes against the conventions and bad for beginner warriors to see it.

Any explanations here?I've solved it ,but didnt get how ,lol

The return type is int but the parameter type is double. I've tried typecasting but keep getting an error saying my types are incompatible.

then what must be used ?

my all tests have passeds except one i don't know whyyyyy

Should be fixed (do verify ~~)

This issue is still not solved.

 call assertEquals(1, keep_hydrated(2))

Error: Type mismatch in argument 'hours' at (1); passed INTEGER(4) to REAL(4)

Simple yet tricky kata, perfect for beginners :)

rounded to the smallest value.

Question is incorrect. If he drinks 0.5L every hour, he should drink 5.5L in 11.8 hours, not 5L as stated in the question.

38.53 hours. rounds to 39. 39 times 0.5 liters = 19.5 liters. NOT 19 liters. so either we don't round, we round down, or he doesn't drink exactly 0.5, soo yeah.

I agree. there was one for 38.53 hours...my solution rounded up to 39 hours, 39 times 0.5 is 19.5, but it 'expected' 19. Doesn't make sense since it tells you to round, and that he drinks 0.5 an hour. I don't think it counts as a coding challenge when the instructions are deliberately not true.
