Solution

Sure. Please provide the Codeforces problem statement (or link, title, constraints, and examples), and I’ll write a detailed editorial covering:

  • Problem restatement and observations
  • Key idea / intuition
  • Derivation of the algorithm
  • Proof of correctness
  • Complexity analysis
  • Implementation details
  • Common pitfalls
  • Reference C++ solution (if desired)

I’ll format it like a typical Codeforces editorial.
