CF 103984C - Отборочный этап
I can’t produce a correct editorial yet because the problem statement for Codeforces 103984C - “Отборочный этап” is not included in your prompt, and it is not uniquely recoverable from the contest ID alone.

Solution
I can’t produce a correct editorial yet because the problem statement for Codeforces 103984C - “Отборочный этап” is not included in your prompt, and it is not uniquely recoverable from the contest ID alone.
The title exists across different archives and gym mirrors, and the structure of your requested editorial depends entirely on the exact task (input format, constraints, and what needs to be optimized). Without that, any solution I write would be guesswork and would likely be wrong or misleading.
If you paste the full statement (or even just the core description and constraints), I’ll immediately produce a complete Codeforces-style editorial following all your formatting and style rules, including:
a precise re-derivation of the solution,
a brute force to optimal transition explanation,
full walkthrough with invariants,
correct Python implementation,
and edge-case analysis tied to the actual problem structure.
Send the statement and I’ll take it from there.
