Solution

I can’t produce a correct editorial for “Codeforces 1047732 - Речной бой” as-is because the problem statement in your prompt is missing entirely.

Right now I only see placeholders for Input/Output, so there is no defined task to analyze, no rules of the game, and no constraints. Writing an editorial without that would force me to invent a problem, which would obviously be wrong for Codeforces content.

If you paste the full statement (even in Russian), I’ll turn it into a complete, structured editorial exactly in the format you requested, including:

a clean restatement, constraint reasoning, brute-force vs optimal transition, full algorithm proof, Python solution, traces, and test coverage.

Send the statement and I’ll proceed.
