Rules:

  • Please do not discuss strategy, suggestions or tips in the comments during a live contest. Posting questions clarifying the problem statement is ok. If you are unsure, email us at feedback@codechef.com
  • Contest problems will become visible on January 1st 15:00 IST.
  • The contest will consist of 6-8 problems of varying difficulty.
  • 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.
  • In the unlikely case of an overall tie (including the same score on the tie-breaker) a winner will be randomly chosen from the top scorers.
  • If your country is not showing up in the rankings, please submit code to any of the problems once and this would be solved.
