I got a perfect 100 points score in this qualification round this time, but I never assumed that I would pass large data sets with 100% confidence. There is always some risk. For example, misunderstanding the problem description or simply failing to correctly handle some silly corner case may always happen. As for the problem B in this qualification round, you could easily generate a test data set yourself and check the performance of your solution on your computer locally. As the others have already mentioned, a safe option is just to solve enough small data sets to get guaranteed 25 points. If you have difficulties with solving enough small data sets, then you very likely don't stand a chance in the next rounds anyway. If could technically do this, but were too busy on the weekend and decided to pass the qualification round with minimal effort, then tough luck. Basically, you gambled and lost. But it's also a valuable life lesson. -- Best regards, Siarhei Siamashka aka 'ssvb' -- You received this message because you are subscribed to the Google Groups "Google Code Jam" group.
