Hello Codeforces!

ZQFMGB12 and I would like to invite everyone to write the Trudeau Logic Evaluation (TLE) 2016 January contest. The TLE is a monthly contest series written by high school students, predominantly from Pierre Elliott Trudeau High School, Canada. The contest serves as preparation for OI-style contests such as the CCO (Canadian Computing Olympiad) and IOI (International Olympiad in Informatics). The contest will be hosted on the DMOJ platform.

The contest will consist of 6 problems, and the problem difficulty will range from Div. 2 A to Div. 1 D. Only problems 4, 5, and 6 will have pretests, and partial points (in the form of subtasks) will be awarded!

The contest window will be 11 hours long and will last from 12:00 EST to 23:00 EST on January 19th, 2017. You may start your 3 hour interval at any time during this contest window, but be wary of the hard deadline at 23:00 EST if you want to start late!

For more information, visit the contest page!

We hope that you will enjoy the contest and that you will receive rating boosts!
