How to speedforces A, B ?

Revision en1, by Nakagawa.Kanon, 2021-05-25 08:32:36

Usually, red coders speedrun A, B very fast while I'm still having trouble reading the statement, and most of the time I found that they're even more annoying to code than C, D, E even thought they're easier. Is it because those problems have appeared frequently and red coders have solved all of them before ?
