April 20th, 2015. The day that Mr. Benum the CS teacher vanished into thin air. It was apparent that Mr. Benum would not be back for a while, so a replacement teacher showed up. He went by "Mr. Venom". A sketchy name, but there's more. He wasn't listed on any teacher database we hacked up; he had no online presence. Even stranger, Mr. Benum had not notified anyone of his absence. And Mr. Venom randomly applied for a job at Thornhill S.S. on the exact day that Mr. Benum disappeared.
No one suspected a thing, except for the members of the computer club. They knew that some shady dealings had occurred, and that they now had to save Mr. Benum from evil forces. Can they rescue Mr. Benum in time to celebrate on this very special day?
Help guide the young investigators rescue their teacher and defeat the evil Mr. Venom in the TSOC '15 #2 Contest!

The contest will run for three days starting on April 20th, 2015. You will have three hours to complete the problems. There will be six problems of increasing difficulty, along with one bonus problem.

dmoj.ca is now available over HTTPS to protect your privacy and identity. We value your security greatly, and have gone to all lengths to ensure that your password is safe and your session remain unhijacked. You can now safely browse

On a related note,
dmoj.ca now delivers its assets over the domain https://dmoj.ml. This is done for performance reasons, mainly to save cookie overhead and better exploit caching. Along with the move of static content to
dmoj.ml, we've also seen fit to drop the
www. prefix of
www.dmoj.ca now redirects to
dmoj.ca (this is why all your visited links are blue again).

The springtime of your adolescence is here! On Thursday, April the 2nd, take part in the 2nd GFSSOC, which will feature separate contests for the junior and senior level. Anyone with a DMOJ account is welcome to participate, and anyone without an account is welcome to register and participate.
The theme of this contest will be past GFSS computer science club head Calvin Liu, who is not with us anymore. RIP Calvin (2010 - 2014)
A reminder for anyone stuck on past GFSSOC questions to visit our organization page, where there is useful information. Detailed solutions for this contest will also be posted here the day after it is over.
Contest ratings similar to TopCoder's rating system have recently been implemented on the DMOJ. Rating is a direct indicator of how likely you are to beat someone else in any given contest. The higher your rating is compared to another person, the more likely you'll place better! There are currently six ranks, based on the numerical value of the rating.
The default rating for users is 1200.
Rating is calculated using your rank on all rated contests you participated in, while also taking into account your competitors.
The ratings displayed on a post-contest scoreboard is the new rating of the user after they participated in the contest.
Update: Contest is over! Ratings are updated, thanks for participating!
