CF 105484L - $P \oplus Q = R$
I’m missing the actual problem statement for Codeforces 105484L - “P ⊕ Q = R” (your template shows it as blank), so I don’t have enough information to reconstruct the task reliably.

I’m missing the actual problem statement for Codeforces 105484L - “P ⊕ Q = R” (your template shows it as blank), so I don’t have enough information to reconstruct the task reliably.
This matters because different “XOR equation” problems can mean very different things: it could be counting triples, solving constraints on bitmasks, reconstructing arrays, or something graph-based with XOR labeling. Each leads to a completely different editorial structure and solution.
If you paste the full statement (or even just input/output + constraints), I’ll write the complete editorial in the exact format you specified, including derivation, algorithm walkthrough, Python solution, and edge-case analysis.
