And Sort

For a given array $B$ of length $M$, a non-negative integer $X$ is said to be **good** if: - The array $C$ of length $M$ defined as $C_i = B_i\space \&\space X$ is sorted in **non-decreasing** order, where $\&$ denotes the [Bitwise AND](https://en.wikipedia.org/wiki/Bitwise_operation#AND) operation. --- Given an array $A$ of length $N$, where $0 \leq A_i \leq N$ holds true for all $i$, count th
