Example: In user give n = 7 Output will be

1 1 开发者_如何学Go1 1 1 1 1

1 0 0 0 0 0 1

1 0 1 1 1 0 1

1 0 1 0 1 0 1

1 0 1 1 1 0 1

1 0 0 0 0 0 1

1 1 1 1 1 1 1

Consider we want to print point (x, y) (the center is (0, 0)). Take max(abs(x), abs(y)) and look if it is odd or even and print 0 for even and 1 for odd.

You should iterate from y = n / 2 to y = - n / 2 and the trough x = - n / 2 to x = n / 2
