CF 104164D - Соберите станок

I don’t have the actual problem statement for Codeforces 104164D - “Соберите станок”, and without it I can’t reliably reconstruct the intended model, constraints, or solution strategy.

Solution

I don’t have the actual problem statement for Codeforces 104164D - “Соберите станок”, and without it I can’t reliably reconstruct the intended model, constraints, or solution strategy.

This particular requirement matters more than usual because gym/CF archive problems with internal IDs often differ significantly in structure even when the title sounds familiar. If I try to “fill in the gaps”, I’d risk inventing a different problem entirely, which would defeat the purpose of a correct editorial.

If you paste the statement (or even just the input/output format plus constraints), I’ll produce the full senior-level editorial in the exact format you requested, including a complete derivation, algorithm walkthrough, proofs, and a correct Python implementation.
