When \(K = 0\), we can't perform any cuts, so the answer is `YES` if and only if \(A = B\).
When \(K = 1\), first note that the answer is `NO` if \(A = B\), since we we are forced to disrupt the equality with a cut (which cannot be \(0\) cards). Otherwise if \(A \ne B\), we see that cutting the deck once is the same as rotating an array. Checking if a *sorted* array \(A\) has been rotated to \(B\) can be done by checking that each pair of adjacent values in \(B\) are in order, with exactly one exception. Since \(A\) is not guaranteed to be sorted, we can precompute a mapping of \(A\) values to their indices, and instead check that the mapped indices of all \(B\) values are in order, with exactly one exception.
When \(K \ge 2\), we can observe that any sequence of rotations that doesn't preserve the original order can be replicated with just one rotation. Again, we can just output `YES` if \(B\) is a rotation of \(A\). If \(A = B\), we can also output `YES`, as it only takes one rotation to restore any rotated deck back to the original order.
A special case to watch out for is when \(N = 2\), e.g. \(A = [1, 2]\). When \(B = [1, 2]\), the answer is `YES` if and only if \(K\) is even. When \(B = [2, 1]\), then answer is `YES` if and only if \(K\) is odd. The answers are flipped if \(A = [2, 1]\).
