Solution

Sure. Please provide the Codeforces problem statement (or a link/title), 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 solution (C++17)

I’ll format it like a typical Codeforces editorial.
