You will receive one point for solving a problem (passing all test cases - no partial credit), regardless of the level of difficulty of that problem.
You can submit solutions as many times as you'd like, there are no penalties for incorrect submissions.
Each contest will have one min/max tie breaker problem, where the best solution will receive one point and all other solutions will receive a fraction based how close they come to the best solution.
Sept 1st, 03:00pm: The final problem will be up in a few hours :)
Sept 1st, 09:20pm: The final problem Counting Hexagons has been added. We apologise for the delay.
