during the contest. Contestants will be disqualified if they violate the
following rules.
計分與排名 Scoring & Ranking
隊伍以解題數量多者排名較前，解題數量相同時，以總消耗時間少者排名較前。
答對的題目的消耗時間計算方式為比賽開始至解出題目所消耗的分鐘數。
如解出前有答錯，每答錯一次需要另加 20 分鐘。
總消耗時間為所有答對題目的消耗時間加總。未答對的題目不計消耗時間。
Teams are ranked according to the most problems solved.
Teams who solve the same number of problems are ranked by least total time.
The total time is the sum of the time consumed for each problem solved.
The time consumed for a solved problem is the time elapsed from the beginning
of the contest to the submittal of the accepted run plus 20 penalty minutes
for every rejected run for that problem regardless of submittal time.
There is no time consumed for a problem that is not solved.
平手判定 Tie-Breaker
解題數與消耗時間均相同時，以先答對最後一題者獲勝。
If multiple teams have the same number of problems solved and total time,
then the winner goes to the team which first submitted their last accepted
solution.
