Need some reviews regarding CSES problemset ?
By pritishn, 5 years ago, In English

Hey everyone,
After watching tmwilliamlin's livestream I was a bit interested in the CSES problemset.
I wanted to ask "Who is it for?" and is it worth it to solve the entire problemset?

I was completing A2OJ ladders (currently in 1700-1800 ladder) till now.
Should I pause that and complete the CSES problemset?

The additional Problems are awesome, you can solve it in part time ,as they are just 200 problems, not as a sprint that is at a stretch, they are more educational I would rather say but indeed they are good to learn many things as the problems are filtered and precise and small, and you would find no editorial of them so you have to hurdle your mind a lot to solve those interesting problems from my side I recommend that one shall solve cses problems , to get a clear picture of some nice DSA topics.

      Will solving CSES Problemset introduce one to new techniques that are commonly used in CP?

        Yes. Not all commonly used concepts, but still, it's a good problemset.

I have only solved the DP section. It's good(read educational) for beginners but a cakewalk for contestants of your level.

Edit: I realized it's an old blog. :D Anyways, that's my review for the DP section for future readers.

Edit 2: Btw, what's your review of other sections if you've solved any of them since this blog?

      People are writing tutorials for different sections. You can find them on CF. Try searching for them.

I've solved all the problems but since got hacked on 2 :(. I now use it as a tested dsa library since it has standard problems and is organized by topic, but if you want that probably this website is better.

All the sections except additional problems are aimed mostly at beginners to introduce them to standard topics, so if you are going to go through them, I suggest going backwards through each one until they are too easy, since as a cm you should have seen most of those algos by now I would think.

However, I think the additional problems are definitely worth your time, they required thinking for me on most of them and use tricks and techniques I see often in problems I solve now. Probably everyone <gm can benefit from at least some of them as some get quite hard.

Oops old blog. Wow tmw's livestream was 3 months ago...

    Nope, I barely know 30-35% of the ds/algos mentioned in https://judge.yosupo.jp . Thanks a lot for sharing this website. I'll try to solve the problems.

      That statement refers to CSES, not judge.yosupo.jp.

      The solutions there are public. You can either access them through the Submissions page, or by clicking on the "Fastest" button on a problem. There, you can adjust the filters as needed.
