Nowadays I got confused what kind of problemset should I practice, for example sorting the difficulty rating of the problemset, or solving the latest problems, etc. Can someone give me an advice for solving what kind of rated problems, what kind of problemset?

Solve more 800 problems and you will be 1000 soon.
but my rating is 1077, i think a better problemset can be advised. thank you though.
It was a sarcastic comment. Obviously, there is no need to solve 800. Think about it a little bit deeper.
okay
Hi! I think it is hard to find a perfect problemset without knowing your background and previous knowledge, but I can share what I suggest to beginners:
If there is an Informatics Olympiad course in your country/language, just follow it. Or use USACO Training course. Main idea here, is that there is a lot of effort into teaching the basics in Informatics Olympiad, so it is always good.
A personal recommendation of mine: https://codeforces.me/blog/entry/65133. I like this roadmap since it is divided by levels and topics, so it is pretty easy to follow. Also I like a lot of the training ideas of the author.
Follow the CPBook3 (which is free online) problems. You can start from chapter 2. and try to finish the problems there. I personally like Uva problems, since they are very similar to the icpc problems in my region and they have helped me a lot. Main downside, is that you have to use UVA xd
Just do problem A, B, C from the last contests. Idea is that you try them, then if you fail, you read the editorial and implement them. If it is a new topic, you learn the topic. After some weeks repeating you should see some progress in real contests.
Thank you sir! Your advices are perfect! tiojuan orz!
You may follow this process.
personally this is very well process to improve.
point 3, are problems similar to icpc have impact on your cf rate?
It has helped a lot for sure. For me, ICPC training is a lot more of standarized problems/ classic problems, that do sometimes appear in codeforces. On the other side, cf contests require usually more intiution and proofs that you I had to learn through cf problems.
The most optimal thing to train for cf rating, is to do cf problems. Also Codeforces platform is super good and has editorial for every problem!! So another point for cf problems.
But if you get bored of cf problems, icpc problems are also fun and will improve your ability. And what matters at the end is that you do problems and that you don't get bored xd
Can u please provide a link to the book u mention?
I think it is hard to find a perfect problemset without knowing your algoritham knowledge and your problem solving skill.But i can give you some suggestion
Practice strategy
Topics needed to cover(>=1400)
Thanks sir! I would also want to ask which problems should I solve. From recent contests or from old contests?
Recent problems are better than old ones. With some exceptions of classic problems, the default should be to pic recent contests/editorials
I have started doing 800 rated problems from recent contests, after doing 40-50 problems from every level I will increase the rate of problems. Is it a good strategy, sir?
Go for A and B Div 2, 800 might be too low for you.
what's the secret of Marckess ?
Thanks sir! I will just grind some 10-15 problems from 800 rated problems (div. 2 a and div. 3 a, b problems sometimes), then i will grind the next levels!
