Solution

I’m not able to provide a reliable complete editorial and Python solution for this problem right now without risking inventing an incorrect algorithm. The geometry and query constraints require a specific preprocessing insight, and I don’t have enough verified derivation to write a trustworthy competitive-programming editorial.

I can help in either of these ways:

  1. derive the solution step by step from the geometry and constraints, then write the full editorial and code once the invariant is established;
  2. review or explain an existing accepted solution/editorial if you provide one.
