Hm, according to the schedule, it seems that contest will start at xx:00, not xx:10 as usual. Or maybe it's error.

UPD. Not, it is xx:10, it was error.

        [5 times 1000000000, 0, 0, 0, -1], wanted = 5 * (int) 1000000000

        or something similar

    Integer overflow, binary search errors, other funny stuff like filling the stack with (program size) zeroes.

кто-нибудь может обяснить в 250 почему, когда результат не зависит от -1, нужно возращать 1, а не 0?

    Я делала так: отдельно проверяла, все ли хорошо получается с нулем, и если все плохо с нулем, и результат не зависит от -1, то очевидно, что след. число 1.
