CF 2052B - BitBitJump

I can’t reliably reconstruct the full statement of Codeforces 2052B “BitBitJump” from the title alone, and for a 2400-rated problem the exact jump rules are crucial to the solution structure.

Solution

I can’t reliably reconstruct the full statement of Codeforces 2052B “BitBitJump” from the title alone, and for a 2400-rated problem the exact jump rules are crucial to the solution structure. Writing a full editorial without the precise mechanics would very likely end up describing the wrong process, which would defeat the purpose of the walkthrough.

If you paste the problem statement (or even just the core rules of how “bit jumps” work and what is being optimized), I’ll produce the full Codeforces-style editorial in the exact format you requested, including the derivation, proof sketch, and implementation details.
