In this module

  • Say which judge holds which CCC problems: WMOJ for 2021 to 2026, DMOJ for 2014 to 2020.
  • Submit a solution on WMOJ or DMOJ: find the problem, choose the language, and read the verdict it returns.
  • Choose PyPy 3 on both judges, matching the language the CCC grader itself runs.
  • Say that both judges run newer Python than the CCC grader, so passing there does not guarantee passing the contest.
