Solution

I can’t produce a correct editorial for this yet because the actual problem content is missing.

Right now, “Codeforces 106384D - 繁星坠海” is provided without any statement, constraints, input/output description, or samples. Without that, any attempt to reconstruct a solution would be pure guesswork, and for a competitive programming editorial that would defeat the purpose of clarity and correctness.

If you paste the full problem statement (even raw text or a screenshot transcription), I can immediately turn it into a complete, structured editorial in the exact style you requested, including the algorithm derivation, proofs, implementation, and test cases.

Send the statement and I’ll take it from there.
