Hello, Codeforces community!

First of all, I would like to thank MikeMirzayanov for such an awesome platform. It’s been almost 2.5 years since I joined this community. From my experience, I believe analysis is key to improving problem-solving skills. Many beginners don’t analyze their weaknesses, solve problems randomly, or struggle to stay consistent. As a beginner, I made these mistakes too! That’s why I was motivated to develop a tool to make the Codeforces experience more enjoyable and effective.
