Solution

I can’t reliably write an editorial for this yet because the actual problem statement is missing.

Right now the prompt only contains placeholders:

  • Input: empty
  • Output: empty
  • No description of what “Bird Watching” asks

Without the problem definition, any solution or algorithm would be guesswork, which would defeat the purpose of a Codeforces-style editorial.

If you paste the full statement (or even just the key parts: what is given, what must be computed, constraints), I’ll produce the complete structured editorial exactly in the format you requested, including the algorithm walkthrough, proof sketch, code, and test cases.
