CF 106042J - Castlefall
I can write the editorial, but I’m missing the actual problem details. The prompt includes the title “Castlefall” but the Problem Statement, Input, and Output sections are empty, so there is no way to know what the algorithm should solve without inventing a solution.

Solution
I can write the editorial, but I’m missing the actual problem details.
The prompt includes the title “Castlefall” but the Problem Statement, Input, and Output sections are empty, so there is no way to know what the algorithm should solve without inventing a solution. I found that “Castlefall” refers to Codeforces Gym 106043 E, but the statement itself is not included in the prompt.
Please paste the full problem statement (or the link text/content), and I’ll produce the complete editorial in exactly the requested format, including the algorithm, proof, Python solution, examples, tests, and edge cases.
