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 . The sign ai denotes the i -th element of permutation a . The modular equality described above denotes that the remainders after dividing ai+bi by n and dividing ci 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<=105) .
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.

说明/提示
In Sample 1, the permutation triple ([1,4,3,2,0],[1,0,2,4,3],[2,4,0,1,3]) is Lucky Permutation Triple, as following holds:
- ;
- ;
- ;
- ;
- .
In Sample 2, you can easily notice that no lucky permutation triple exists.
