CF 1047761 - Прямые и окружности

I can’t reliably write a correct editorial for “Codeforces 1047761 - Прямые и окружности” without the actual problem statement. Right now I don’t know: - what the inputs represent (geometry? queries? construction?

Solution

I can’t reliably write a correct editorial for “Codeforces 1047761 - Прямые и окружности” without the actual problem statement.

Right now I don’t know:

  • what the inputs represent (geometry? queries? construction?)
  • what is being asked (counting intersections, distances, tangency, etc.)
  • constraints, which determine whether this is geometry, combinatorics, or data structures

If you paste the full statement (or even just input/output + constraints), I’ll produce the full editorial in the exact format you requested, including derivation, optimal approach, proof sketch, and code.
