Solution

I don’t have the actual statement for Codeforces 103150I “X-OR XOR”, so I can’t safely derive a correct editorial yet. With XOR-style problems especially, small missing details completely change the intended solution (range vs. prefix, updates vs. static array, counting vs. construction, etc.), so guessing would risk producing a misleading write-up.

Paste the full problem statement (including input/output format and constraints), and I’ll turn it into a complete, structured editorial in the format you specified, including intuition, algorithm derivation, code, and edge-case reasoning.
