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.
