CF 103118D - Dyson Box
I can’t reliably write a correct Codeforces editorial here because the problem statement is missing. “103118D - Dyson Box” isn’t included in your prompt, so anything I produce would be guesswork.

I can’t reliably write a correct Codeforces editorial here because the problem statement is missing.
“103118D - Dyson Box” isn’t included in your prompt, so anything I produce would be guesswork. For a Codeforces editorial, that would be especially risky since the entire solution structure, constraints, and algorithm depend on details like what the “box” does, what operations are allowed, and what needs to be optimized or computed.
Paste the full problem statement (or even just input/output + constraints), and I’ll turn it into a complete senior-level editorial in the exact format you specified.
