I want to increase my problem-solving abilities(rating ) for which I am currently solving problems topic-wise (but unfortunately my rating on codeforces and other online judges isn’t improving ).
I need advice on how should I practise: topic wise? upsolving? difficulty wise? or random?
It would be very generous if you guys can share your strategies and advice me
in which direction should I move.
PS: I am currently participating in long challenges and codeforces(div2) rounds.
