DMOPC '17 November Contest
Welcome to the second Don Mills Open Programming Competition of the 2017-2018 season!
The problem writers this time are
and .If this is your first time participating in the DMOPC, you can learn about our system here.
This round will be rated for all participants who submit at least once.
Before the contest date, you may wish to check out the tips and help pages.
This contest will consist of main 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 (noon EDT of Nov. 15th), whichever comes first.
Additionally, this contest will feature a -th problem (Problem ) for students who are just getting started with programming.
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:
- Start from the beginning. Ties will be broken by the sum of times used to solve the problems starting from the beginning of the contest. The last submission time of your highest score 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
stdin
/stdout
to perform input / output, respectively. - It is guaranteed that all the problems will be solvable with C++.
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.

Comments
When are the rankings going to be added?
I'm pretty new at DMOJ, so I was curious if the solutions/hints/participant's solutions to the problems will be available after the end of this contest (It wasn't written anywhere and I still don't know how to solve P5). So will they be published? Thanks in advance.
Once the editorials are written (which should be by tonight), they will be provided in a link on each problem page. They will also be available on this page in a table. I'm glad you enjoyed the problems!
I learned today that sometimes one should actually read the problem before trying to solve it.
Great contest btw!
(I predict that REEmark is d)
EDIT: I think that this contest already broke the record for most number of rated (submitted at least once) participants. Congrats!
Any clarification on P6 - Lazy Days when it states "Maximizes the Minimum?"
I've posted a reply on the problem page. In the future, please ask questions on the problem page (which is private), not on a public page.

I follow that link, and it takes me to the problem page. There are no comments there.
Alright, I've temporarily added the comment into the output specifications of the problem.
