There will be two coding challenges. Each challenge has a predetermined score.
Your score for a problem depends on the number of test cases your submission successfully passes.
You will be ranked on the basis of the score that you get. Only your best correct submission will be considered.
In case of a tie, the rankings will be determined by Total Time Penalty, which is the sum of the total time elapsed from the start of the contest when the participant submitted the best submission plus a penalty of 10 minutes for every rejected submission (Wrong answer, Time limit exceeded, Runtime Error) for reaching the best score. The lower your Total Penalty, the better.
The time elapsed or penalty is not considered for any unsolved problem.
