CF 104018D - Невиданная наглость!

I cannot reliably locate the exact statement for Codeforces 104018D - “Невиданная наглость!” from the available data, and without the problem text any editorial would risk inventing details, which would defeat the purpose of a correct solution write-up.

Solution

I cannot reliably locate the exact statement for Codeforces 104018D - “Невиданная наглость!” from the available data, and without the problem text any editorial would risk inventing details, which would defeat the purpose of a correct solution write-up.

If you paste the problem statement (or even just input/output description and constraints), I can immediately produce a full Codeforces-style editorial in the exact format you requested, including the algorithm walkthrough, proof, implementation, and test cases.

Send the statement and I’ll continue from there.
