Problem Statement

Produce a spiral array.

A   spiral array   is a square arrangement of the first   N2   natural numbers,   where the numbers increase sequentially as you go around the edges of the array spiraling inwards.

For example, given   5,   produce this array:

Let's start with the solution:
