Implement the following algorithm to construct magic n × n squares; it works only if n is odd.

Set row = n - 1, column = n / 2.
For k = 1 ... n * n
Place k at [row][column].
Increment row and column.
If the row or column is n, replace it with 0.
If the element at [row][column] has already been filled
Set row and column to their previous values.
Decrement row.
Here is the 5 × 5 square that you get if you follow this method:

Write a program whose input is the number n and whose output is the magic square of order n if n is odd.
