Solution

I can’t write a correct, detailed Codeforces editorial for 105862H - Expected Value Of Function without the actual problem statement.

Right now the input/output section is missing, so I don’t know what the function is, what randomness (if any) is involved, or what structure we’re optimizing over. For expected value problems, those details completely determine whether the solution is combinatorics, DP on subsets, linearity of expectation, inclusion-exclusion, or something else entirely.

Please paste the full problem statement (or even a screenshot / raw text), and I’ll produce a complete editorial in the exact style you requested.
