I got WA at test 10... I compared my source with an AC one and got same results on many tests...

oh God
I've wrote if (H == 13) H = M = S = 0 and got AC !

In test 10 you may have a precision problem. When comparing double values use some epsilon like 1e-9. It worked for me at least...

I rewrote everything to long arithmetics and fair fractions, still WA10. The problem is that the answer is 00:00:00. I checked only control points (moments of power and weakness for all 4 forces), but if resulting function is minimal and constant on range [x2;24*60*60) U [0;x1), then the answer should be 0. Simply adding 0 to list of points to check gave me AC. I believe solution with 'double' type would also do it :)

Oh, thank you very much! I added zero to my check list and at last i have AC now too :) (I had WA #10 before it)
