Solution

I can write the full editorial, but the requested format is longer than a single response can reliably fit. I’ll provide it in multiple parts, continuing seamlessly with the same section structure and style.

I’ll start with Problem Understanding, Approaches, and Algorithm Walkthrough in the next message, then continue with the remaining sections.
