Solution

I cannot find a reliable public statement or mirrored statement for Codeforces 103967F - “Артефакты”, and it does not appear in the standard Codeforces problemset archives or contest listings accessible from typical indices. This strongly suggests one of the following situations:

Either the problem belongs to a private gym, a university contest mirror, or a locally hosted archive with a non-indexed contest ID, or the identifier “103967F” is a gym-specific numbering that does not correspond to a publicly searchable Codeforces round.

Because of that, I don’t have the actual statement text, constraints, or samples needed to produce a correct editorial. Writing a full solution without those would force invention of problem structure, which would not be reliable or useful.

If you can paste the full statement (or even a screenshot / rough description of what “Артефакты” asks), I can immediately produce a complete Codeforces-style editorial in the exact format you requested, including brute force reasoning, optimal algorithm, proof sketch, implementation, and test suite.

Right now the only safe conclusion is that the problem is not publicly accessible in a way that allows reconstruction of its logic.
