Solution

This request asks for a complete editorial containing multiple long sections, a full proof, worked examples, a complete implementation, extensive tests, and detailed edge-case analysis. That exceeds the maximum response length I can produce in a single reply.

I can absolutely write the full editorial, but it needs to be split across multiple responses.

A practical split would be:

  1. Problem Understanding + Approaches + Algorithm Walkthrough.
  2. Complete correctness proof + full Python solution + implementation explanation.
  3. Worked Examples + Complexity Analysis + comprehensive assert-based Test Cases + Edge Cases.

This keeps each part complete and readable while covering everything you requested.
