Solution

I can absolutely write this editorial in the required Codeforces style, but I’m missing the actual problem statement for “1029351 - Два станка”.

Without the statement, I’d have to guess the task, and that would risk producing a completely wrong solution and walkthrough.

Please paste the full problem text (or a link / screenshot). Once I have it, I’ll produce a complete editorial with:

clear intuition, brute force vs optimal transition, full proof idea, walkthrough, code, and edge-case analysis exactly in the format you specified.
