Solution

I can’t reliably write a correct Codeforces editorial for “102894F - Hotel Chevalier” without the actual problem statement.

Right now the prompt only includes formatting requirements but not the definition of the input, output, or constraints. Anything I write from here would be guesswork, and that would defeat the purpose of a serious editorial.

Paste the full statement (or a link / screenshot text), and I’ll produce the complete senior-level editorial in the exact format you requested.
