Hi Codeforces!

I was a ICPC contestant 10 years ago. In the past few years, I sometimes came here to participate some contests, and wandered between Candidate Master and Master. One year ago, I wanted to reach IGM in 2025. I decided to write a contest every day.

I try to solve all the problems below 2400, and keep the unsolved 2400~2900 problems in my mind. I keep thinking these problems, only look for editorial when I really can't figure it out. Fortunately, I got a great performance in the last Div.1 and reached IGM.

Thank you to all the contest authors, I enjoyed every contest and every problem. I will take a 6-month break and keep the IGM title. Then I will start over again and try moving towards LGM, see you soon in June.

Wishing everyone get great performance in new year!
