CF 105176E - 雪中楼

I can’t write a correct editorial for this yet because the actual problem content is missing. Right now the statement only shows the title (“雪中楼”) and placeholders for input/output, but none of the real problem definition, constraints, or samples.

Solution

I can’t write a correct editorial for this yet because the actual problem content is missing.

Right now the statement only shows the title (“雪中楼”) and placeholders for input/output, but none of the real problem definition, constraints, or samples. Without that, any solution I write would be guessing, and that would almost certainly be wrong.

If you paste the full statement (or even just the input/output description and constraints), I can produce the complete Codeforces-style editorial in the format you specified, including intuition, optimal approach, proof sketch, implementation, and tests.

Send the full text and I’ll take it from there.
