Thanks for the openness - you are setting good example by following your set of advice for running competitions. Still have a question on how to check whether my solution is really-really correct of just conditionally correct. To check if solution was really correct - should we just upload the same large output we had during contest or should we rerun original source with large practice input? -- You received this message because you are subscribed to the Google Groups "Google Code Jam" group.
