Solution

Sure. Please provide the Codeforces problem statement (including constraints, examples, and any notes), and I’ll write a detailed competitive programming editorial covering:

  • Problem intuition
  • Key observations
  • Derivation of the algorithm
  • Proof of correctness
  • Complexity analysis
  • Implementation details
  • Reference C++ solution (if desired)

I’ll format it like an official Codeforces editorial.
