CF 105540K - The Devil
I don’t have the actual problem statement for Codeforces 105540K - The Devil in your prompt (the “Problem Statement / Input / Output” sections are empty), so I can’t correctly reconstruct the task or derive a valid solution.

Solution
I don’t have the actual problem statement for Codeforces 105540K - The Devil in your prompt (the “Problem Statement / Input / Output” sections are empty), so I can’t correctly reconstruct the task or derive a valid solution.
For a Codeforces editorial, the exact rules of the problem are essential. Even small differences (graph vs DP vs greedy, constraints, or what the input represents) completely change the solution, so I’d risk inventing a problem if I proceeded.
Paste the full statement (or even a screenshot / raw text), and I’ll produce the complete editorial in the exact format you requested.
