I can absolutely write this editorial in the exact format you want, but I’m missing one critical piece: the actual statement of Codeforces 103181D - Markat.
Right now the “Problem Statement / Input / Output” sections are empty in your prompt, so there’s no way to reconstruct what the problem is about (graph, strings, DP, geometry, etc.). Any attempt to proceed would be guesswork and would produce a fake solution.
Please paste the full problem statement (or even just a short description of what Markat asks), and I’ll produce a complete, Codeforces-style senior-level editorial with:
- clean re-derivation of the idea,
- brute force → optimization story,
- full algorithm walkthrough,
- correct Python solution,
- worked traces and edge cases,
- and complexity justification.
Once you send it, I’ll write the full editorial in one go.
