CF 105974C - Distinct Xor Subsequence Queries Ⅱ
I’m missing the actual problem statement for Codeforces 105974C - Distinct Xor Subsequence Queries Ⅱ, so I can’t reliably reconstruct the task or the intended solution path.

I’m missing the actual problem statement for Codeforces 105974C - Distinct Xor Subsequence Queries Ⅱ, so I can’t reliably reconstruct the task or the intended solution path.
Right now, the title suggests something about XOR subsequences and queries, but that’s not enough to determine:
- what exactly is being queried (counts, existence, k-th value, etc.)
- whether subsequences are contiguous or not
- constraints (which completely change the technique: trie, linear basis, DP, etc.)
If you paste the full statement (or even just the Input/Output + constraints + one sample), I’ll produce the full editorial in the exact format you requested.
