Hi, I am a beginner in code forces and till now I have solved multiple problems for A and B and even some of C and D and E too. Still, I was not able to perform even in a single question correctly in DIV 2 A (Round 664 Div2). Failed pretest 2 times with the wrong answer and 1 time with TLE.
I want helpful tips from the community. Please do comment if u some helpful guidelines for me. I don't know what I am doing wrong.
For practice, I follow A20J ladders. Even today I did solve 5 B problems(but with a lot of errors and submissions ) before the contest but during contest round, I don't know this happened. It will be helpful if someone guide for increasing my accuracy. Please comment if you have anything important note for me.
Thank you
should have tried problem b.
Try to solve div-3, problems are easier than div-2.
You can also participate virtual contests, so that you will get familliar with platform and questions and it will help you in real contests .
After completion of each contest/problems, you can check other's solution, eventually you will come across some great solutions for that same problem.
Try to make a mashup of 26 A div 2 problems and then solve it. Div 2 A problems are only about adhoc and implementation. Speed-solving them.
