Solution

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

  • Problem restatement and key observations
  • Intuition behind the solution
  • Step-by-step derivation
  • Algorithm
  • Proof of correctness
  • Complexity analysis
  • Implementation details
  • Reference C++ solution (if desired)

I’ll format it like an official Codeforces editorial, with emphasis on the ideas that lead to the solution rather than just the final technique.
