Solution

The problem statement is missing from the prompt, so I can’t reconstruct what “Knights of the Frozen Throne” is asking for or derive a correct solution.

For Codeforces editorials, the exact rules, constraints, and operations matter a lot, and guessing would very likely produce a wrong algorithm.

Paste the full statement (or even a screenshot/text dump), and I’ll write the complete editorial in the exact format you specified, including:

clean restatement of the problem
brute force → optimization transition
full algorithm walkthrough
correct Python solution
worked traces, edge cases, and tests

Once you send it, I’ll proceed directly.
