Solution

I can write the full editorial, but I’m missing the actual problem statement for Codeforces 102964E (“Krosh and expected value problem”).

Right now the input/output section is empty, so I don’t know:

  • what the random process is (if any),
  • what probability or expectation is being computed,
  • what operations or structure Krosh interacts with,
  • what constraints drive the solution.

Without that, any “editorial” would just be invented and very likely incorrect.

Paste the full problem statement (or even a screenshot/text dump), and I’ll produce the complete structured editorial exactly in the style you requested.
