Hi, codeforces users. In the beginning of summer, I did set a goal to reach the expert level on codeforces. However, I didn't manage to achieve this goal. So, I am starting the grind again. In the upcoming 3 days, there are 3 contests, and I will participate in each of them. Hopefully, I will manage to raise my rating to 1400 (my current is 1025).

If you are familiar with my previous blogs, recently I had my final exams. Finally, they are over and now I can focus on competitive programming. My initial goal was to reach expert by the end of summer. Since today I will participate in every contest and solve plenty of problems in order to achieve my goal. If you wanna compete, let me know.

Hello, Codeforces!

I am a relatively new user of Codeforces, and I do not really understand what should I do to improve. So, basically:

1. I just solved rating + 200, rating + 300 problems to grind, but it did not help as well as expected.
2. I participated at contests and upsolved. However, it did not help as well.
3. I learned new algorithms(like segment tree, mo's algorithm, dp tricks). But as you know, user does not need complicated algorithms until rating of 1600 or even higher.

I have heard that following certain roadmap is way better than solving random problems and found plenty of them. For example, Competitive Programming Roadmap (target: [gray, blue]), A Way to Practice Competitive Programming and etc. So I have question, which roadmap is better and what should I do?

Hi. My previous blog post got so many downvotes. To be honest, I did not understand why would they do it, but it won't change me! In 1 month I will have my external exams and currently I am not able to grind in CP. However, I will become expert by the end of summer or even earlier. Wish you good luck!

Hello y'all! I have taken 5 contest so far and my goal is to become expert. I know, that there are so many blogs about it. However, I will update my state and show my progress in this blog. I have no idea, whether I am going to reach my goal. Wish me good luck!

I have already seen editorial, but getting WA. Here is the problem and this is my code. Can you please help me?

Thanks!
