Overwrite

You are given two arrays $A$ and $B$, of lengths $N$ and $M$ respectively ($M \leq N$). All the elements of $A$ are distinct, and all the elements of $B$ are distinct — that is, $A_i \neq A_j$ for $i \neq j$, and $B_i \neq B_j$ for $i \neq j$. In one operation, you can do the following: - Choose a subarray$^\dagger$ of $A$ with length $M$, and replace it with a cyclic rotation$^\ddagger$ of the
