Solution
I can’t write a correct Codeforces-style editorial for “102896N - New Flat” yet because the actual problem statement is missing.
Right now I only see the template sections (input/output placeholders), but none of the key information: what the “flat” consists of, what operations are allowed, what needs to be computed, or even the constraints. Without that, any solution would be a guess, and that would defeat the purpose of a proper editorial.
Please paste the full problem statement (or at least the description, constraints, and sample input/output). Once you send it, I’ll produce a complete editorial in the exact format you requested, including the reasoning, algorithm walkthrough, code, proofs, and edge-case analysis.
