constructing a square matrix of edge N, and its element should not be same across same row and column

问题

So, I was constructing a matrix (square) of length N, its element i should between 1 <= i < 2 * N

• Each element should be between 1 to 2 * N - 1
• for each i and j (1 <= i <= N and 1 <= j < 2 * N) the j element should appear in ith row / i column

for any N
if the desired matrix is not possible we have print -1;

Which means for N = 2

We could get matrix as -

1 2
3 1

As we can see for 1st row and column we can get 1 , 2 , 3. and for 2nd row and column we get 1, 2, 3

Another example : for N = 4

1 2 4 6
3 1 6 5
5 7 1 3
7 4 2 1

please help.
