Hi everyone!

The Div. 3 round has just ended, and I'd like to share my thoughts.

I think problems A and B were a nice warm-up and quite straightforward. Problem C required a bit more observation, and after that the difficulty increased significantly.

I solved 1 problems and learned a lot from this round. I spent the most time on problem 10 minute, where a small mistake cost me a lot of time.

I'm curious about everyone else's experience:

• Which problem did you enjoy the most?
• Which problem was the hardest for you?
• Did you find any clever observations or interesting solutions?

Congratulations to everyone who gained rating, and good luck in the next contests!
