  1. You may not discuss the problems with anyone outside of your team. However, discussion within your team is highly encouraged.
  2. You may consult the internet or use pre-written code. Articles, websites, and videos are all fair game. But you may not ask others questions on the internet or make any posts during the contest window.
  3. You may code on any IDE installed on your computer, or you can code directly on Hackerrank.
  4. If you have any questions, raise your hand and staff members will come and help! Staff members may provide assistance in reading input and submitting code, but not on the problems themselves.


  1. Each problem is worth 100 points, meaning there is a maximum score of 1000.
  2. For each problem, there will be 10-20 test cases among which the 100 points will be split. Your score for that problem will be the fraction of the test cases you get correct multiplied by 100.
  3. Rankings will first be counted by total score, with the last submission time being used as a tie-breaker.
