Wesley's Anger Contest 2

It is well known that wleung_bvg is always angry. To vent out his anger, he decided to create a contest. He also roped in Zeyu and Pookmeister to help create some problems.

This time, all problems will have some Halloween component. Here are the parameters of the contest:

  • Contest duration: 3 hours.
  • Number of problems: 6, full feedback. Each problem will be worth 100 points, with no subtasks.
  • Rated for all participants who submit at least once.
  • Scoreboard will be visible.
  • No submission limit.
  • Each non-AC (excluding Compiler Errors) submission will have a penalty of 5 minutes towards your submission time for that problem.
  • Ties will be broken by the last submission time that increased your overall score, plus penalty minutes.
  • Checkers for problems: Unless otherwise specified, identical. The contest will follow the standard convention of having all lines terminate in a \n character, with no trailing whitespace.

Furthermore, users are forbidden from using multiple accounts or collaborating during the entire contest duration. Any suspicious behaviour during the contest window may result in a severe penalty including, but not limited to, being placed at the bottom of the scoreboard. Such behavior includes, but is not limited to:

  • Registering for the contest with at least two accounts.
  • Participating in the contest with an account that is not your primary account.
  • During the contest window, talking about the contest in more detail than answering a yes/no question about whether one participated in the contest. This includes, but is not limited to, posting spoilers about the contest and public speculation of the contest.
  • Attempting to exploit bugs in the platform to subvert the constraints of the contest.

The problem setters for this contest are wleung_bvg, Zeyu, and Pookmeister.

Special thanks to Dormi, crackersamdjam, and Plasmatic, for providing feedback and testing the problems.

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

This contest will consist of 6 problems, the difficulty of which may range anywhere from CCC Junior to CCO level. For this contest, all problems will have some Halloween component.

You will have 3 hours to complete the contest. After the contest window begins (3:00 PM EDT of October 31st), you may begin at any time. Once you enter the contest, your personal timer will start counting down and you will be able to submit until 3 hours from when you started, or until the hard deadline (11:59 PM EDT of November 2nd), whichever comes first.

After joining the contest, you can 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:

  • It is not guaranteed that the problems will be in order of increasing difficulty. Reading all of the statements is recommended.
  • 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++ and Java. All problems have a time limit of at least 1.5x the reference solution, which is written in C++ and uses this template for I/O. If you're unable to see the template, you must solve this problem. Problems that have been tested in multiple language may have language specific time limits.

At the end of the contest, you may comment below to appeal a judging verdict. In the case of appeals, the decision(s) of DMOJ staff is final.

    If anyone wishes to contest any aspect of the contests such as claims of cheating or may still wish to request an unrate because they were affected by DMOJ's downtime, please contact Pookmeister or wleung_bvg on Slack with proof.

    How long does it usually take for a DMOJ contest to be rated?

      You should expect it to take a few days, as we need to perform checks to look for cheaters.

    There was previously an issue with DMOJ being down at around 8:45pm EDT to 9:05pm EDT on November 2nd. We apologize for the inconvenience. Anyone may request to be unrated through Slack by messaging Pookmeister or wleung_bvg if they have proof that they were significantly affected by this issue.
