Is A2 oj really helpful to improve my rating in codeforces ?↵
And when practicing in codeforces how to choose difficulty level of question as a newbie or pupil ?↵
Note : I can solve div-2 A easily but div-2 B is hard to me and I can't solve div-2 C with out reading editorial (But I have to spend huge time to understand the editorial of C ).↵
Thanks in advance. : )
