Hi, everyone!

I had WA#9 too, but I wrote 'long double' instead of 'double' and got AC. It means it was precision's trouble.

I had the same problem.
changing double to long double didn`t help,
but adding 0.0001 to the result before casting it to int got my code AC.
Apparently it`s an epsilon problem.
