Sure - I can do that, but I need the problem first. Please paste the full Codeforces problem statement (or at least the key parts: input/output format, constraints, and statement). If you also have a link or contest/problem ID, that works too.

Once I have it, I’ll write a proper competitive programming editorial with:
- intuition
- step-by-step reasoning
- optimal approach
- complexity analysis
- implementation notes (and code if you want)
