Sure. Send me the Codeforces problem statement (or link, title, and constraints), and I’ll write a competitive programming editorial with:
- Problem restatement
- Key observations
- Derivation of the algorithm
- Proof of correctness
- Complexity analysis
- Implementation details
- Reference C++17 solution (if you want)
I’ll write it in the style of a Codeforces editorial: focused on the intended insight rather than just the final technique.
