Hello everybody,
I'm trying to improve my level on codeforces, so I always try to solve hard problems for me
like C and D Div2 but in 95% I can't solve them my self so I read the tutorials and I
feel that I'm still in the same place after solving good number of C and D problems and I am still
not able to solve C in most cases.
I should tell you that I am practicing alone and I have no coach and just depending on
the web to learn.
So I will be thankful if you tell me how to practice and if there are any resources that I have to learn from?
Thanks.
don't read much from the editorials. just saying, it's not good unless you have thought about the problem for like 4 hours (sum of your thinking)
I think this may help you. this is Codeforces Practice Ladders — A2 Online Judge made by Ahmed_Aly.
Patience all what u need keep doing C,D then E and about the tutorial it will take awhile to solve with out it but for now keep doing this
