Balanced and Unique Arrays

For a positive, $\textbf{even}$ integer $N$, we call a pair of arrays $A$ and $B$ to be **interesting** if they satisfy the following conditions : - $|A| = |B| = N/2$ i.e. the length of array $A$ is equal to the length of array $B$. - Each integer from $1$ to $N$ occurs exactly once in exactly one of the arrays. - The $i^{th}$ prefix sum of $A$ is not equal to $i^{th}$ prefix sum of $B$ for all
