Solution

I can write the full editorial in the requested format, but the problem statement for Codeforces 105910D - MIS again is missing. I cannot reliably reconstruct the problem, constraints, examples, or intended algorithm from the title alone, and I do not want to invent details that would make the editorial incorrect.

Please paste the actual problem statement (or a link to the problem page), and I’ll produce the complete editorial with all requested sections, including the Python solution, walkthrough, examples, tests, and edge cases.
