AIM Tech Codeforces Round will take place on February, 4 at 20:05 MSK.
The round is prepared by AIM Tech employees: Kostroma, riadwaw, yarrr, ArtDitel, ValenKof, bobrdobr, agul, gchebanov and zeliboba. Round will take place during Petrozavodsk Winter Camp, which is sponsored by our company.
We made our problems a little easier than at our last Round, but we promise they won’t be less interesting. Scoring system will be static. The final distribution of points will be announced right before the round, however you should note that this time difference in complexity between problems div1 C, D and E may be less than usual so our strong recommendation that you read them all first.
Our company specialises in proprietary trading, the key concepts in our work are big data, low latency and high frequency. Our team mainly consists of graduates from the MSU Faculty of Mechanics and Mathematics and Moscow Institute of Physics and Technology (MIPT).
We wish you good luck and high
