题目描述
A permutation $p$ of size $n$ is the sequence $p_{1},p_{2},...,p_{n}$ , consisting of $n$ distinct integers, each of them is from $1$ to $n$ $(1<=p_{i}<=n)$ .
A lucky permutation is such permutation $p$ , that any integer $i$ $(1<=i<=n)$ meets this condition $p_{pi}=n-i+1$ .
You have integer $n$ . Find some lucky permutation $p$ of size $n$ .
A lucky permutation is such permutation $p$ , that any integer $i$ $(1<=i<=n)$ meets this condition $p_{pi}=n-i+1$ .
You have integer $n$ . Find some lucky permutation $p$ of size $n$ .
输入格式
The first line contains integer $n$ ( $1<=n<=10^{5}$ ) — the required permutation size.
输出格式
Print "-1" (without the quotes) if the lucky permutation $p$ of size $n$ doesn't exist.
Otherwise, print $n$ distinct integers $p_{1},p_{2},...,p_{n}$ $(1<=p_{i}<=n)$ after a space — the required permutation.
If there are multiple answers, you can print any of them.

你好,我是作答助手。可以问思路、复杂度、样例含义或代码报错原因;不会直接给出完整 AC 代码。
