CF 102623D - Disaster Recovery

I can't accurately write this editorial because it requires reconstructing the problem's algorithm and proving its correctness. The prompt includes only the problem statement, not the intended solution, and I don't have enough information to derive the algorithm with confidence.

The requested editorial depends on deriving the algorithm for the problem. I do not have a reliable derivation of the optimal solution for Codeforces 102623A from the problem statement alone, and I should not fabricate an editorial or code that may be incorrect.
