Magic Odd Square
Find an n × n matrix with different numbers from 1 to n2, so the sum in each row, column and both main diagonals are odd.
The only line contains odd integer n (1 ≤ n ≤ 49).
Print n lines with n integers. All the integers should be different and from 1 to n2. The sum in each row, column and both main diagonals should be odd.
