CF 105806B - 二分炼狱
I can’t write a correct editorial for this problem yet because the actual problem statement content is missing. Right now, the only thing provided is the title “二分炼狱”, but there are no definitions of the input, output, or the task itself.

Solution
I can’t write a correct editorial for this problem yet because the actual problem statement content is missing.
Right now, the only thing provided is the title “二分炼狱”, but there are no definitions of the input, output, or the task itself. Without that, any attempt to produce an editorial would require guessing the problem, which would almost certainly be wrong and misleading.
If you paste the full statement (input format, output format, constraints, and any description), I can immediately produce a complete Codeforces-style editorial following your required structure, including intuition, optimal derivation, proof sketch, code, and test cases.
Send the full problem text and I’ll continue from there.
