Bad solution received AC

Posted by ryu 3 Nov 2008 22:20

I wrote bad solution, but my program received AC.
My friend gave me test:
0 1 7
0 1000 1
45 1000 1
90 1000 1
135 1000 1
180 1000 1
225 1000 1
270 1.25 60
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.

Please check the checker again. It seems to me that it passes some tests even when my program outputs zeroes as numbers of ships.

Checker does not accept zeroes.
