Solution
Sure-please paste the full Codeforces problem statement (or at least the problem link / contest + problem letter).
Once I have it, I’ll write a proper competitive programming editorial with:
- intuition
- key observations
- step-by-step solution
- proof of correctness
- complexity analysis
- (and code if you want, in C++ or Python)
Send it over.
