So recently i started doing competitive programming after a break. What I notice from practice or participation in a contest is that, I'm not able to solve B problem in div2 and C in div3 and finally C(sometimes) and D in div4. Are there any resources that contain the topics to solve these problems?
I felt bad for not solving a problem after taking a long time on it(especially div2 B). Could you guys suggest any tips and resources? Also as a newbie , should I spend a lot of time on a problem before looking at the editorial ?
Any suggestions would be helpful! Thanks
Spend time as long as new ideas are coming, if you can't think of anything new read hints/ editorial line by line. If you can't solve B solve around 900-1200 rated problems randomly and B's from previous contests. For B you don't need to spend 1hr thinking about the idea so if it's taking too long just read and understand editorial and what you missed while thinking, Learn it and move on and train more.
