Solution

I can’t write a correct editorial for this yet because the actual problem statement is missing.

Right now I only see the title “Range Xor Subsequence Query”, but none of the definitions of:

what a query asks, what a valid subsequence means in this context, how XOR is applied, or what needs to be computed.

Given Codeforces problems, that missing structure completely changes the solution class (it could range from segment tree, trie DP, Mo’s algorithm, or even bitwise combinatorics), so any attempt to proceed would just be guessing.

If you paste the full statement (or even just input/output + constraints + one sample), I’ll produce a complete, structured editorial in the exact format you requested.
