How to be quick at solving A and B.
By ghostwriter, history, 4 months ago, In English

I'm having some trouble solving A and B (the last round for example), when it comes to greedy or some tricky problem, all the things I can do is wasting 1 hour to solve B (and sometimes A).

if you are having hard time concentrating on the problem then you must try https://m1.codeforces.com/ I was also having this issue then I started to use this during contest there are no options to see standings, no clock, just problem and option to submit, so beautiful it helped me a lot.

    I guess he is asking about getting the approach to solve A and B quickly.

In order to AC QA/B quickly, you have to code the correct solution for the corresponding problem in a short time.

Used to (and still sometimes does) happen to me as well.
Sometimes first solving C/D and then coming back to A & B can be helpful.
As you have already solved a 'harder' problem by the time you come to A/B, you have an idea about their difficulties and don't end up complicating your approach.

Bro you've solved 544 problems,and you could easily solved C and D problems, I don't see any valid reason for asking this question.

NB: i know i'm not an expert but i think that should work. if you think it won't you can just ignore it. I think you've solved lot of hard problem and you are good at it. but for increasing speed you have to solve some easy problem too. I would like to advice you to participate atcoder Beginer contests,problems are very easy but speed will increase i hope. That worked with me dunno about you guys.

    If that worked for you , why are you still a newbie...Solving A and B under one hour would easily get you into pupil.

try to think of simple solutions, more often than not, if your solution is becoming too messy or complex, you're over complicating it

first guess, and try to prove the simple approach you get(or use examples to check them), write codes

that can be done really fast in a contest, make sure you come up with the simplest and most obvious method
