Solution

I cannot write a reliable editorial for this problem from the information provided because the actual statement, input format, output format, and samples are missing. The title alone is not enough to determine the exact task, and there are multiple spiral-related problems with similar names and structures.

Please provide the full problem statement (especially the missing sections under Problem Statement, Input, and Output) or paste the samples. Then I can produce the complete editorial with the requested sections, proof, Python solution, traces, tests, and edge case analysis.
