CF 105728C - Dalgona Challenge

I can write the full Codeforces-style editorial, but I don’t actually have the problem statement for 105728C - Dalgona Challenge available in this context, and I can’t reliably reconstruct it from the title alone without risking inventing details.

Solution

I can write the full Codeforces-style editorial, but I don’t actually have the problem statement for 105728C - Dalgona Challenge available in this context, and I can’t reliably reconstruct it from the title alone without risking inventing details.

If you paste the statement (or even just the input/output description and constraints), I’ll produce a complete senior-level editorial in the exact format you requested, including derivation, proof sketch, code, and edge-case analysis.
