I agree with numerix. My best solution will fail for several cases. But due to weak test data it got accepted.

Too much accounts for one guy I think.

I regret to say, there exist some indications that Rully Soelaiman (arena) might be a cheater. That would be devastating, because I believed that he was brilliant coder worthy of position next to Oleg and Xilinx, not a cheater.
I have posted 1 problem on spoj, and my friends many more. They all say that Rully posted someone's code. As for my problem this is true, and I disq his solution.
Please look into it. If I am wrong I apologise to all of you, especially to Rully for saying this stuff.
The following I can confirm for my problemset PRIMPERM23:
The solution of Rully Soelaiman32, submitted on 02-05-2011, is byte by byte identical to the solution of Tegg62, submitted on 29-04-2011.
I have seen him submitting solutions to multiple problems under a minute. But he has also solved several difficult problems having less than 10 AC solutions. May be he is some kind of professor in the institute having access to spoj account of all students.
User alrezza21 (name of the ancients) has 450 problems solved within a single week, submitting one solution after another. Must be a genius.

I'm sorry, but again it is very obvious that Rully Soelaiman15 continues submitting others solutions:
Solutions to NWERC11A .. NWERC11J are those of Jonathan Schmidt-Dominé ...
Every single one of Rully Soelaiman's submissions to my problems have been either one of the judges' official solutions, or solutions taken out from different Chinese blogs which are not his.

I really don't like this unresolved situation. Rully Soelaiman is/was one of the top users and I think it's a high priority. His account is still active and he once is and once isn't on the ranking list. Please resolve this situation and either clear him of cheating suspicions or delete the account with all the submissions, so that they are also not included in specific problem lists.
That doesn't look like real problem solving: https://www.spoj.pl/status/souptikpro/36
I also doubt that. Too many tough problems solved in HASK on the first attempt. I think that happens if people publish their solutions, which cant be avoided.
Marked activity these last three days.
I'm not here since many times, but imho, this situation is very strange. So silent.
I saw him on AU1215, a very easy problem, with few submissions, his solution seems to have different memory usage than the ones with similar execution time.
But so many suspicions were shown...
