CF 103810C - Фуршет
We are missing the actual statement of Codeforces 103810C, and this is not publicly inferable from contest metadata alone. Without the problem text, any “editorial” would be fabrication rather than explanation, which would defeat the purpose of a Codeforces-style writeup.

Solution
We are missing the actual statement of Codeforces 103810C, and this is not publicly inferable from contest metadata alone. Without the problem text, any “editorial” would be fabrication rather than explanation, which would defeat the purpose of a Codeforces-style writeup.
If you paste the full statement (or even just input/output description plus constraints), I can produce the complete editorial exactly in the format you specified, including full derivation, optimal approach, walkthrough, code, and edge-case analysis.
Send the statement and I will continue immediately.
