I can’t write a correct editorial yet because the actual problem statement for Codeforces 105858K - Darkness Rise isn’t included in your prompt. Right now I don’t know what the input represents, what needs to be computed, or what constraints drive the solution.

Solution
I can’t write a correct editorial yet because the actual problem statement for Codeforces 105858K - Darkness Rise isn’t included in your prompt.
Right now I don’t know what the input represents, what needs to be computed, or what constraints drive the solution. Without that, any “editorial” would inevitably become a guess, and that defeats the goal of being something a reader can re-derive a solution from.
If you paste the full statement (or even just the key parts: what’s given, what must be computed, constraints, and samples), I’ll produce a complete Codeforces-style editorial in the exact format you requested, including the brute force transition, full correctness reasoning, and a tested Python solution.
Send the statement and I’ll take it from there.
