Croatian Open Competition in Informatics

Yesterday, the 1st contest of COCI 2007/2008 was held. It was from 9 to 12PM WIB (GMT+7). There were 6 tasks for contestants to solve in 3 hours. The environment system used in this contest is the same as the IOI 2007 system.

The solution, usually the committee will publish it officially in a few days after the contest, but I will try to publish mine here. So far, I’ve only full-scored 4 tasks (the 1st, 2nd, 3rd, 5th) and partial-scored the 6th task (did brute force).

For the OSN 2007 medalists, if you didn’t have enough time yesterday to compete, you can try the analysis mode. And if you really want to practice, try not to do “trial n error” way, try to fully solve and code the tasks in 3 hours without any help and then submit all your source code and see the score you can get. After you get your score, you can post your mark here as a comment. I will make a short list of OSN 2007 medalists’ rank in 1st contest of COCI 2007/2008. Enjoy this event as a warm-up for the 1st TOKI 2008 National Training which will be held on 12 November - 2 December 2007.

    Timotius NC : 96
    Huweee….I could only afford 96 out of 300 points [not even the one third]….
    The other OSN Medalists might had been too tired after ComputerCompetition@Gonzaga…..
