Can anyone give me some tips about solving constructives quickly on codeforces pls? Now what I'm doing is smth like random guessing (I cannot find the right method quick often), and if I failed, I get stuck on that problem for a long time!
Example: In Codeforces Round 953 (Div. 2) I get stuck on C (constructive) for about 40min and therefore get a low ranking(although I solved D and E fast). This kind of things often happens on me and that's kinda annoying.
Sorry for poor English. Any help will be appreciated.
how do you solve 3000+ rated problems?
I can solve it after understanding the tutorials.
tbh I feel like there is no special guide to solve these problems fast and I`d say that problem C is more about math. Usually the key idea of that kind of problems is relatively simple. I guess there is no other way besides practicing more.
off-topic , but can you share your training method ? How did you train in your initial days ?
