The problem statement section in your prompt is empty, so there isn’t enough information to derive the task, constraints, or required algorithm. Without that, any editorial would be guessing, which defeats the purpose of a Codeforces-style writeup.

Solution
The problem statement section in your prompt is empty, so there isn’t enough information to derive the task, constraints, or required algorithm. Without that, any editorial would be guessing, which defeats the purpose of a Codeforces-style writeup.
If you paste the actual statement (or even just the input/output description and constraints), I can produce a full editorial in the exact format you requested, including the algorithm walkthrough, proof sketch, Python solution, and edge case analysis.
Send the statement and I’ll continue from there.
