Like I want to practice Div2C today where can I go? There is no provision for it on codeforces but yes we got a2oj so there i can practice the Div2C. What if i want to practice problems with tag "dfs and similar" of codeforces? I got the tag feature in the problem set.
What If I want to practice Div2C problems containing the tag "constructive algorithm" of codeforces? Does anybody know how to have a list of those problems?
I don't think that you will find a list like that .
but it doesn't matter whether it is div 2 c or div 2 b .
the most important thing is its difficulty , you can find a div 2 b problem which is harder than div 2 c problem it depends on the contest .
a2oj put a sorted all dfs and bfs problems based on their difficulties so you can solve the problems based on their difficulties .
a2oj.com is good option to find problems the way u want.
Actually, nowadays one can just go to CF problemset and use the "Filter problems" field to the right. Tags and problem difficulty points make it very easy.
bro help...how can i use filter to find the problems of div.2 C problems??
AFAIK, there is no specific filter for A/B/C etc. problems. However, Div.2 C problems usually have difficulty in the range of 1400-1800. So I would use https://codeforces.net/problemset?tags=1400-1800.
