题目描述

Bike is interested in permutations. A permutation of length $n$ is an integer sequence such that each integer from 0 to $(n-1)$ appears exactly once in it. For example, $[0,2,1]$ is a permutation of length 3 while both $[0,2,2]$ and $[1,2,3]$ is not.

A permutation triple of permutations of length $n$ $(a,b,c)$ is called a Lucky Permutation Triple if and only if ![](/uploads/acgo/image/27a58a89ac02b822_5b98adee2839.jpeg). The sign $a_{i}$ denotes the $i$ -th element of permutation $a$ . The modular equality described above denotes that the remainders after dividing $a_{i}+b_{i}$ by $n$ and dividing $c_{i}$ by $n$ are equal.

Now, he has an integer $n$ and wants to find a Lucky Permutation Triple. Could you please help him?

输入格式

The first line contains a single integer $n$ $(1<=n<=10^{5})$ .

输出格式

If no Lucky Permutation Triple of length $n$ exists print -1.

Otherwise, you need to print three lines. Each line contains $n$ space-seperated integers. The first line must contain permutation $a$ , the second line — permutation $b$ , the third — permutation $c$ .

If there are multiple solutions, print any of them.
