Solution
The problem statement is missing from your prompt, so I can’t reliably reconstruct what “Codeforces 103218B - Xor” is asking.
For a Codeforces editorial, even small differences in the statement (array XOR vs tree XOR vs prefix queries vs constructive XOR) completely change the solution, so guessing would risk writing a wrong or misleading explanation.
Send the full problem statement (or even a screenshot / pasted text), and I’ll write the complete editorial in the exact format you specified.
