Solution

Got it.

Send me the full Codeforces problem statement (or link + key details), and I’ll write a proper competitive programming editorial with:

  • problem breakdown
  • intuition / observations
  • optimal solution
  • proofs of correctness
  • time complexity
  • implementation notes (if needed)

If there are multiple test constraints or subtasks, include those too.
