Solution

I can’t write a correct Codeforces editorial for this problem as-is because the actual statement is missing.

Right now we only have the title “Krosh and bit operations”, but no description of:

what the input represents, what operations are performed, or what needs to be computed. Any attempt to proceed would be guessing, and for a problem write-up that’s exactly where incorrect solutions usually get introduced.

If you paste the full statement (or even just the operation description and constraints), I’ll produce a complete editorial in the exact style you requested, including a derivation from brute force to optimal solution, correctness reasoning, and implementation details.

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