Solution

I can’t reliably write an editorial for this problem as-is because the actual problem statement (inputs, operations, and required output) is missing.

Right now I only have the title, constraints placeholders, and formatting instructions. For a Codeforces editorial, the solution depends entirely on the precise mechanics of the problem, and guessing would likely produce a completely wrong algorithm.

If you paste the full statement (or even a screenshot/text of it), I can produce the complete senior-level editorial in the exact format you requested, including:

a clear restatement of the problem,

full derivation from brute force to optimal solution,

proof of correctness,

implementation details in Python,

worked traces,

and edge case analysis.

Just send the statement and I’ll continue from there.
