Yesterday, I was solving this problem 1175D - Array Splitting from Educational Codeforces Round 66 (Rated for Div. 2). Initially, it was rated as 1900, and after reading it, I spent around 15 minutes with no idea. I was about to give up, but for some reason, I decided to attempt an approach using prefix sums. After outlining my idea on my board, I quickly realized the solution was simple. I implemented it, and after 35 minutes from the start, I got it accepted on the first submission.
Is it a good performance to solve a 1400-rated problem in 35 minutes?
Has recalling a problem you've already solved ever made a difference in a CP event like winning?
it's not your fault to use memory in past, since if you didn't use that then there isn't difference between upsolve problems or not XD
Yeah. I think I have such a memory because that contest was on December 02 (over 7 months now)and I was able to recall it properly 😂
GM memory right there, now all you have to do is solve 2K more problems.
Btw what is your average time for solving 1400 problems?
Yeah, GM memory is not talked about too much.
Recently I have been challenging myself to solve only problems rated 1600 or higher during practice so I can't answer your question. I think that most of the time I will be able to solve a 1400 problem during a contest so there is no real need for training on it. You can check on my recent live contest where I would have probably solve 1400 problems and see the time I used.
