Welcome to the first Don Mills Open Programming Competition of the 2015-2016 school year!
The problem writers this time are cheesecake, Xyene, and FatalEagle.
This round will be rated for all participants.
We are using a new format for the competition this year. The DMOPC will be a 3-hour virtual contest, which will allow contestants to participate in any 3-hour window between 12PM EDT and 9PM EDT. Of course, it is forbidden to use two accounts to participate, and it is also forbidden to discuss the problems and/or their solutions with other people during the entire contest period.
Another change is that system tests will be run after the contest period ends, as an additional measure to prevent cheating. During the contest, on problems 4, 5, and 6, when you submit, you will receive your result on some of the test data, called preliminary tests (pretests). If you pass all the pretests, you will get a (temporary) score of 1/1 for that problem. After the contest, we will rejudge all solutions on the complete set of test data, and that will determine your final score, out of 100, as usual. Note that getting AC on pretests does not necessarily ensure you will pass system testing.
It's guaranteed that all subtasks will show up at least once in the pretest.
You will not be able to view partial output during the contest.
The theme for this month's contest is GATE.
The contest consists of 6 questions with a wide range of difficulties, and you can get partial marks for partial solutions in the form of subtasks. If you cannot solve a problem fully, we encourage you to go for these partial marks. The difficulty of a problem may be anywhere from CCC Junior to CCO level. You will have 3 hours to complete the contest. After the contest window begins, you may begin at any time. 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 (9PM EDT), 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:
- 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.
- 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++.
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.
After the contest finishes, we'll have a optional feedback form we would like you to fill out.
