Solution
The prompt is missing the actual content of Codeforces 103640E - Expedition Plans (problem statement, input/output description, constraints, and samples).
Without that, any editorial would be guesswork and likely incorrect, especially for a Codeforces problem where the solution hinges on specific structure (graphs, DP, greedy, etc.).
Please paste the full problem statement (or at least the key parts: description, constraints, and sample I/O). Once you do, I can write the complete editorial in the exact format you requested.
