Solution

We are missing the actual statement of Codeforces 103458D in the prompt you provided. The problem name “Тренировки миротворцев” (“Peacekeepers’ training”) exists, but the task description (what is given, what must be computed, and constraints) is not included. Without that, it is impossible to write a correct editorial, since the solution strategy depends entirely on the underlying model (graph, DP, greedy, data structure, etc.).

Please paste the full problem statement (input/output description and constraints). Once you provide it, I will produce the complete Codeforces-style editorial exactly in the format you requested, including reasoning, algorithm derivation, implementation, and test cases.
