Increasing XOR Queries
An array $B$ is called *good* if the prefix XOR array is non-decreasing. Formally, the following condition should hold: - For all $1 \le i < j \le |B|$, $B_1 \oplus B_2 \oplus .... \oplus B_i \le B_1 \oplus B_2 \oplus ... \oplus B_j$. You are given an array $A$ with $N$ integers, and need to answer $Q$ queries of the following form: - Given $L$ and $R$, is $A[L, R]$ *good* where $A[L, R]$ repr
