Solution
Sure. Send me the Codeforces problem statement (or link, title, constraints, and examples), and I’ll write a detailed competitive programming editorial with:
- Problem restatement
- Key observations
- Derivation of the solution
- Proof of correctness
- Complexity analysis
- Implementation details
- Reference C++17 solution (if you want)
I’ll write it in a Codeforces editorial style, focusing on the reasoning path and why the algorithm works.
