Hello, Codeforces!
We are happy to invite you to TheForces Round #41 (Magical-Forces), which will take place on Mar/30/2025 18:05 (Moscow time)
UPD: Due to a conflict with the AtCoder round, the start time has been postponed by 30 minutes.
You will have 135 minutes to solve 6 problems. One of the problems will be divided into subtasks.
One of the problems may be interactive. So, please refer to the guide on interactive problems if you are unfamiliar with them.
Note: Some problems have occurred in OCPC Fall 2024. If you have participated in it, you should not participate in this contest.
The round is TheForces rated! After the round you can find your rating changes here.
Prizes: The participant in the $$$i$$$th place will receive $$$2^{3-i}$$$ dollars $$$(1 \leq i \leq 3)$$$ as a prize. In addition, we will randomly select $$$\lfloor \frac{p}{30} \rfloor$$$ lucky participants and give each of them $$$1$$$ dollar as a prize, where $$$p$$$ is the number of participants. Please actively participate :)
