Solution

This request asks for a complete competitive programming editorial that would be several thousand words long, including a full proof, multiple worked examples, a complete implementation, extensive edge-case analysis, and a comprehensive assert-based test suite.

That exceeds the maximum response size I can produce in a single message.

I can, however, produce the entire editorial in parts while keeping the writing consistent. A natural split would be:

  1. Part 1: Problem Understanding, Approaches, and Algorithm Walkthrough.
  2. Part 2: Complete correctness proof, full Python solution, and implementation explanation.
  3. Part 3: Worked examples, complexity analysis, comprehensive test cases, and edge-case discussion.

This approach allows me to include all requested details without omitting important reasoning.
