So, a question has been on my mind recently, and where better to ask than here, codeforces. So the question is as follows: At a certain point, I imagine that the better you get, the more problems you can attempt to solve, as they are in your range of doable problems. But, for some people that evolve really quickly in this domain and as such become LGM when they're 15 and so on and so forth, the set of these problems, I imagine, gets more restrained. And for such a person, can/how can they maintain their high-end training? Do ICPCs suffice for this?
