Revision en2, by _Muhammad, 2017-10-16 19:16:28

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. : )
