Good Luck! Hope to see you participating.
I reckon, that the statement of DARTS is awful. No examples on communication process, russian and english versions of the statement are different in some key points(For example, in the english one there's said, that we can choose N by ourselves, while the russian one claims that it's provided in the input and it's always equal to 100 000. Which of these two versions is correct? ). Also, the checker doesn't seem to be OK, cause I keep on getting WA verdicts with negative time of running. Seriously, the checker says that my solution runs in -1 seconds. Does anybody know what does it mean?
But the thing, that annoys me the most is that nobody of admins answers questions about the statement!
So, I ask admins to be more responsible and to start making something to resolve the problems I described above.
Thanks.
Hi kostya_by,
the correct is the english version, you can choose N for how many darts you throw in training mode, it is between 0 and 100000.
Sry I didn't get your questions just now. I checked your solution, and run it with the offline tester, and it is write to me "your code still running", becuase you use too much dart. (I still don't know what is -1 on the server but maybe you write too the std output when the judge didn't expected,( the judge is finished example)..)
The point is if you are at kind of stage where you cannot finished the 501 game with double your darts what is in your hand it would became "used". (you cannot finished if you overflow, or you don't finished with double the 501 or you have one score left because you cannot finished the game from here.)
To better understaning try this:
start to the offline tester:
java -jar Darts.jar -deviation 0.0
after that you just throw triple 13, after the 12 dart throw your score will be 468 and the used darts is 12. and next turn is start (three dart is in your hand again) if you throw triple 13 again your score is overflow you cannot finished the current stage the 501 game so this turn became invalid, and you lose the other two dart what is in your hand too.
So your score would became 468 again and you used 15(!) darts.

iscsi
PS: Sorry my english.
It seems you've get -1 time if you setup N less than 0 or more than 100000. Or throw a darts outside of the 1.2 circle. We will try to fix it soon, sorry.
