Welcome to the second DMOJ Monthly Open Programming Competition of the 2020-2021 season!
The problem writers this time are, , and .
Please note that this contest will be full feedback.
Please note that this contest will have a different tiebreaking scheme from earlier contests. (See below for details.)
This round will be rated for all participants.
This contest will consist of 6 problems, the difficulty of which may range anywhere from CCC Junior to CCO level.
Some problems offer partial marks in the form of subtasks. If you cannot solve a problem fully, we encourage you to go for these partial marks.
You will have 3 hours to complete the contest. After the contest window begins, 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 (00:00:00 EST of December 7th), whichever comes first.
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:
- Ties will be broken by the sum of submission times. The last submission to each problem will be used.
- 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
stdoutto perform input / output, respectively.
- It is guaranteed that all the problems will be solvable with C++.
Clarification requests for the contest must be routed through the clarification system provided on DMOJ, and not through other channels including but not limited to Discord and Slack. Furthermore, all clarification requests will be handled the way they normally are in IOI. Note that, in particular, clarification requests must come in the form of yes/no questions.
Due to rampant issues with cheating on contests that has happened recently, any suspicious behavior during the contest window may result in your rating being impacted negatively. 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.
Punishments may include performance being unrated or, for more serious infractions, being forcibly ranked at the bottom of the scoreboard.
