Two Dementional Array Spiral Fill
How could i write two methods... one recursive and one not to fill a two dementional array of size n.
ex. 5 x 5 array
0 1 2 3 4
15 16 17 18 5
14 23 24 19 6
12 22 21 20 7
12 11 10 9 8
the non-recursive routine would be like void spiralFill(int a, int n) where it spiral fills the first n rows and columns

There are a couple of ways to do this, but we wont do it for you! What have you come up with for ideas thus far?
For the non-recursive way, think about how you would go adding to each element in the array. It may help to do the non-recursive part first, then move onto the recursive part (assuming you're a newer student, this would be easier).
Think about how he array's are filled, and how you could possibly loop that.
Let us know what you come up with.
