2. The total penalty: all through the title of (consuming the number of errors * + 20 minutes) and did not pass the subject is not the time penalty.
3. rankings, problem-solving priority number, the same number of questions sorted by time penalty.
Information for participants
1. Participants are required to independently ensure the answer is in the range permitted by the rules;
2. Any group or individual may illegally copying the premise without the organizers allowed the subject, the subject of data theft, if the violation, Comet OJ right to pursue their legal obligations;
