What kind of knowledge or skills are needed to solve 1500-rated problems?
By SHADOW088, history, 3 hours ago, In English

I've been trying to improve on Codeforces, and I'm currently aiming to solve 1500-rated problems. However, whenever I read the problem statements of some 1600-rated questions, I feel completely lost.

What concepts or implementation skills should I focus on to bridge this gap and make consistent progress? I'd love to hear your thoughts, advice, or personal experiences!

    Any tips on how to build it? I know practice is key, but what kind of practice should I focus on? Like, what specific topics or types of problems would help in building intuition?

There is not really any knowledge or special skills you need for 1500 rated problems, just reasoning and thinking. Maybe binary search and prefix sums. Just keep practicing.
