A permutation of length $n$ is an array $p=[p_1,p_2,\dots,p_n]$, which contains every integer from $1$ to $n$ (inclusive) and, moreover, each number appears exactly once. For example, $p=[3,1,4,2,5]$ is a permutation of length $5$.

For a given number $n$ ($n \ge 2$), find a permutation $p$ in which absolute difference (that is, the absolute value of difference) of any two neighboring (adjacent) elements is between $2$ and $4$, inclusive. Formally, find such permutation $p$ that $2 \le |p_i - p_{i+1}| \le 4$ for each $i$ ($1 \le i < n$).

Print any such permutation for the given integer $n$ or determine that it does not exist.
