Solution

Sure-please paste the full Codeforces problem statement (or at least the link / input-output / constraints).

Once I have it, I’ll write a proper competitive programming editorial with:

  • Key idea / intuition
  • Step-by-step reasoning
  • Formal solution
  • Complexity analysis
  • Common pitfalls
  • Reference implementation (C++/Python if you want)
