Before the contest, you may wish to check out the tips and help pages.

The contest will run from Jan 1, 12AM EST to Jan 5, 12AM EST. It will consist of 3 problems.

After joining the contest, you proceed to the Problems tab to begin. You can also go to Users if you wish to see the rankings.

We have listed below some advice as well as contest strategies:

  • Remove all extra debugging code and/or input prompts from your code before submitting. The judge is very strict — most of the time, it requires your output to match exactly.
  • Do not pause program execution at the end. The judging process is automated. You should use stdin / stdout to perform input / output, respectively.
  • It is guaranteed that all the problems will be solvable with C++.

Good luck and Happy New Year!
