  1. REEmark (perfect score)
  2. mmaxio (perfect score)
  3. y0105w49
  4. zhouzixiang2004
  5. kobortor

Editorials for each of the problems have been uploaded to the respective problem pages.

We hope you enjoyed the contest, and see you next month!

Additionally, mmaxio found an error in the P2 problem statement. This round will still be rated, but if anyone feels that they were affected by this mistake, then comment or contact us on Slack before the next contest, and we will cancel that your rating change from this contest.

Dishonourable mention to windowat, Dreamweaver, and Weendowat for being the same person and cheating on the contest. We apologize if we didn't refer to you by your preferred username. A second dishonourable mention goes to goodpotato02 and 1419903188; we find your ability to solve P0 in <30 seconds to be quite impressive, if not completely falsified.

Starting this year, there will be a couple changes to the DMOPC/DMPG.

Starting with this DMOPC:

  1. The DMOPC will return to being a monthly contest, from last year's almost monthly format.
  2. The top 20 Canadian High School contestants across all rounds will automatically qualify for the DMPG Gold Division.

As for the DMPG:

  1. There will still be 3 divisions: Bronze, Silver, and Gold.
  2. The Bronze and Silver Divisions will be open to all.
  3. The Gold Division will be open to the top 20 Canadian High School contestants across the DMOPC rounds, and there will be prizes given to the top coders.

Note that this is subject to change.

On Tuesday, November 14th, we'll be hosting the November Don Mills Open Programming Contest!

Anyone with a DMOJ account is welcome to participate, and anyone without one is welcome to register and participate.

Contestants may participate in any 3-hour window between noon EST of Nov. 14th and noon EST of Nov. 15th. Please see the contest page for more details.

See you soon!
