Solution
The problem statement for Codeforces 103895C - Ellie the Elephant isn’t included in your message, so I don’t have the actual rules, input format, or required computation to base an editorial on.
Right now anything I write would be guesswork, and for a Codeforces editorial that would break correctness immediately.
Please paste the full problem statement (or at least the core description + input/output + constraints). Once you do, I’ll produce the complete editorial in the exact format you requested, including:
a clear restatement, constraint-driven insight, full derivation from brute force to optimal solution, step-by-step algorithm walkthrough, Python implementation, and full edge-case analysis.
