I started learning C++ STL and learned topics like Vectors, Maps(2), and Sets(all 3), now I would like to start solving questions involving these concepts. So can anyone guide me on how to find questions related to these 3 on codeforces? Please don't dislike if this is a repeated question or if I said something wrong.
Thanks in advance!
I know one problem: 1800C2 - Powering the Hero (hard version).
