We welcome you to this year's Valentine's Day Contest! Because the CCC is coming up, the Valentine's Day Contest will be in CCC format, with two divisions, each with five problems each to solve in 3 hours, with a maximum of 50 submissions per problem. The window will open at 9AM EST on the 14th and will run until 9PM on the 16th.

We'll be running both junior and senior divisions. Please see the respective contest pages for more details.

Problem setters for this contest are Ninjaclasher, Rimuru, Beautiful_Times, c, crackersamdjam, and richardyi25.

The Canadian Computing Competition is in just over a month! Once again, a mock CCC has been prepared for individuals wishing to get additional practice for the CCC.

The first mock CCC this year will run during the weekend of January 19th. The junior and senior divisions do not share any problems, so you can participate in both if you want additional practice! Although we announced beforehand that the senior contest would be rated, it will no longer be rated.

We expect all contestants to write the mock CCC under real CCC conditions. Please read the rules on the contest page to ensure that you are in compliance. In particular, we would like to remind all contestants that you may not use any pre-written code.

Good luck to everyone writing the CCC!
