DMOPC Exam Time

posted on Jan. 10, 2015, 9:21 p.m. 0

Update: Thank you to all who participated!
If you were not able to take part (probably due to actual exams), below are the problems for you to solve post-contest:

French Homework
Physics Duel
Chemistry Homework
Exam Delay
Happy Teachers
Math Homework


The first Don Mills Open Programming Competition of 2015 will be held on Tuesday, January 13 from 3:30 to 8:30 PM.

There were initially no plans for a January Contest due to exams, which is why Sentient came up with a contest based on exams! Therefore you may think of this as the January Contest, except that it will be 5 hours long rather than the usual 3 (the difficulty will remain similar to previous DMOPCs and it should take most participants about an hour to solve the first 3 problems).

You can access the contest page here.

Back in the days students were forced to choose between studying for their school exams and participating in programming contests. No more will they have to endure such harsh conditions! With the creation of the Exam Time Contest, you can prepare for your exams as you complete the questions in this contest.

Moreover, what was supposed to be an ordinary exam week at Don Mills takes a turn for the extraordinary in the last few problems.

The Phantom of the Opera

posted on Dec. 22, 2014, 5:10 p.m. 0

Oh no, the Phantom has kidnapped Christine Daaé and is about to force her into a marriage with him. Raoul, the vicomte de Chagny, is anxious to stop this, and make Christine marry him instead return freedom to Christine. The Persian, an old acquaintance of the Phantom, is also determined to stop the Phantom's terrorism of the Opera house, and to save Christine from a forced marriage, joins in with Raoul.

The Phantom hid Christine inside his house on the lake under the Opera house, well guarded. Can you help the duo break through all the defences to save Christine? We know that the Phantom, like any other crypto nerd, likes prime numbers...

The pressure is on. Solve these problems!

  • The Mirror
  • The Third Cellar
  • The Torture Chamber
  • And the ultimate challenge: Phantom's Python Challenge

New Site Host

posted on Dec. 6, 2014, 8:40 p.m. 0

We've migrated the DMOJ site to a new hosting provider, Linode. There should be noticeable (positive) differences in page load speed compared to before, and no more load time spikes. That being said, expect minor instabilities as we finish up migrating background services.
