What topics should I look at in programming olympiads? What are some helpful resources on these topics?

Question

Programming

I decided to take up Olympiad programming, because it gives a bonus when entering a university. I know C++ quite well, I programmed in QT, I'm moving to UE4. The main thing is to advise topics on Olympiad programming. Optional - resources where you can find their analysis

Answer 1

Well, first of all, it's real math. It will greatly help to reduce the execution time of the same type of things (as the sum of all numbers from 1 to 100).
There are also a large number of sites for participating in tournaments (sometimes trial ones). Just check your experience - that's it.
All this is easily googled, unless of course you already use it.
