The first line contains three integers $n$, $k$, and $s$~--- the total number of sectors, the number of remaining questions, and the sector containing the ``Hyperblitz'' question ($1 \le n \le 10^9$; $1 \le k \le \min(n, 200)$; $1 \le s \le n$). It is guaranteed that $n$ is not equal to $998\,244\,353$.

The second line contains $k$ distinct integers $q_1, q_2, \ldots , q_k$~--- the numbers of sectors that still have envelopes, in clockwise order ($1 \le q_1 < q_2 < \ldots < q_k \le n$).

There is exactly one index $i$ with $q_i = s$.
