Let $m_{i, j}$ m_{i,j} be a two-dimensional array of size $n \times n$ n \times n, where $m_{i, j} = i + j$ m_{i,j} = i + j. The array is $1$ -indexed, $m_{1, 1}$ m_{1,1} is the top-left corner of the matrix. Print the array.

Input

One positive integer $n (n < 50)$ n~(n < 50).

Output

Print the two-dimensional array. Each number must be printed using exactly $2$ character positions.
