Solution
The problem information provided here is incomplete, so a correct editorial cannot be written yet.
Right now, the statement only shows a label “M” without any description of the input format, output format, or task definition. For a Codeforces problem, those are the entire substance needed to derive any algorithm. Without them, there is no way to know whether this is a graph problem, a greedy scheduling task, a string problem, or something else entirely.
Because of that, any attempt to write an “editorial” would be pure guesswork, and it would almost certainly describe the wrong problem.
If you can paste the full statement of Codeforces 105806M - 晚饭吃什么？ (including input, output, and constraints), I can immediately produce a complete, structured editorial in the format you requested.
