Candidate solution routes
Primary
FreeBitwise invariants / XOR cancellation
Invariant: The running XOR equals the XOR of values with odd processed frequency; per-bit counts can be reduced independently modulo a repetition count.
candidate confidence: 0.560 · metadata_only
How to use this page
Read the statement and constraints first, then validate recognition signals, invariant, and complexity. Candidate score is not correctness evidence.
