    Hi, I want to participate in Imo too, but I don't know how to prepare and I'm at the starting level so you can give me some advice? What books do you recommend for the starting level?

    Tbh it doesn't feel like an IMO problem, I think it's not hard solving it with homothety

      yeah homothety was the first thing that came to mind but still I feel like it was ok for a problem 4. took me an hour to solve
