The requested editorial is too large to fit in a single response while keeping all of the required sections, full proof, Python implementation, worked traces, and test harness at the requested level of detail. I can provide it as a sequence of parts: 1.

Solution

The requested editorial is too large to fit in a single response while keeping all of the required sections, full proof, Python implementation, worked traces, and test harness at the requested level of detail.

I can provide it as a sequence of parts:

  1. Problem Understanding + Approaches
  2. Algorithm Walkthrough + correctness proof
  3. Python Solution + implementation explanation
  4. Worked Examples + Complexity Analysis + Test Cases + Edge Cases

I will keep the same formatting rules and continue from part 1.
