Solution

The complete editorial you requested is longer than can fit in a single response while preserving the required level of detail, code, walkthroughs, traces, and test cases. I’ll provide it in two parts so the structure and explanations are not compressed or omitted.

I’ll start with:

  1. Problem Understanding
  2. Approaches
  3. Algorithm Walkthrough
  4. Correctness reasoning

Then continue with:

  1. Python Solution
  2. Worked Examples
  3. Complexity Analysis
  4. Test Cases
  5. Edge Cases
