What should I do? | | I have WA6. Please anybody HelpME! | 107th | 1655. Somali Pirates | 10 Aug 2020 14:40 | 4 | Maybe it's because of accuracy? (in case you are still alive) was it because of accuracy ? I was using doubles and got WA8 due to precision error, but then I changed all of the doubles to pair<long long, long long> (trying to represent them as rational fractions without any loss of accuracy) and got AC.

1 Most of your tests are incorrect)) "All numbers contain at most three fractional digits". But they are surely useful.
I can't say this problem is so hard. I had only some problems with accuracy. These tests may help:

P. S. Can you give me some hints on 1672?

all hints are unhelphull.
We are, old mathematitians have habbit
to use cost function, restrictions
and sequence of points set under refimement procedure
to find optimization result. | | Bad solution received AC | ryu | 1655. Somali Pirates | 22 Nov 2008 13:31 | 5 | I wrote bad solution, but my program received AC.
My friend gave me test:

90 1000 1
135 1000 1
180 1000 1

My program output "Impossible", but solution exists.
Ships should be shot in the order:
1 7 6 5 4 3 2 2 ADMINS: Testset is really weak - my program contains several rude mistakes, nevertheless - AC.
Please, add new tests or fix bug in checker... There was a bug in checker. All wrong verdicts were rejudged. Thank you for help. Re: Fixed (+) Vedernikoff Sergey (HSE: EconomicsForever!) 22 Nov 2008 03:48 Please check the checker again. It seems to me that it passes some tests even when my program outputs zeroes as numbers of ships. |
