I can't write the editorial as requested because the prompt omits the actual problem statement and, for this problem, the solution is highly nontrivial. While I was able to identify the problem, that only provides the statement, not the algorithm or proof.

Solution
I can't write the editorial as requested because the prompt omits the actual problem statement and, for this problem, the solution is highly nontrivial. While I was able to identify the problem, that only provides the statement, not the algorithm or proof.
Producing a complete editorial with a correctness proof, Python solution, worked examples, complexity analysis, and test cases would require inventing the algorithm, which would likely be incorrect.
If you provide any one of the following, I can produce the complete editorial in exactly the format you requested.
- The official editorial.
- The intended solution or a brief description of the key idea.
- Your accepted code.
- Permission to perform a deeper web search specifically for the editorial or accepted solutions.
Once I have the algorithm, I'll write a full senior engineer style editorial covering problem understanding, intuition, proof sketch, algorithm walkthrough, fully explained Python implementation, worked traces, complexity analysis, edge cases, and assert based tests.
