Solution
I don’t have the actual statement of Codeforces 102978B - Bit Operation in your prompt, only the title. Without the rules of the operation, input format, and required output, I can’t reliably reconstruct the intended solution or write a correct editorial.
If you paste the full problem statement (or even just the core description and constraints), I’ll produce the complete editorial in the exact format you specified, including brute force intuition, optimal bitwise reasoning, walkthrough, and tests.
