Sure. Please provide the Codeforces problem statement (or a link/name/number), and I’ll write a detailed competitive programming editorial covering:
- Problem restatement
- Key observations
- Derivation of the algorithm
- Proof of correctness
- Complexity analysis
- Implementation details
- Reference C++17 solution (if desired)
I’ll format it like an official Codeforces editorial.
