## The Problem - Verbatim |
|
|
|
|
|
|
|
Write a small program which: |
|
|
|
|
|
|
|
accepts on the command line an odd number N |
|
|
|
|
|
|
|
outputs a sequence of numbers corresponding to the following steps: |
|
|
|
|
|
|
|
the numbers 1 through N^2 are written in a grid |
|
|
|
|
|
|
|
the first number in the sequence is the number in the center of the grid |
|
|
|
|
|
|
|
the subsequent numbers are found by spiraling out clockwise, starting to the right |
|
|
|
|
|
|
|
For example, for N = 3 we have the grid: |
|
|
|
|
|
|
|
``` |
|
|
|
1 2 3 |
|
|
|
4 5 6 |
|
|
|
7 8 9 |
|
|
|
``` |
|
|
|
|
|
|
|
So we start with 5, head right to 6, then down to 9, left through 8 and 7, up through 4 and 1 and finally right through 2 and 3. This gives the output: |
|
|
|
5, 6, 9, 8, 7, 4, 1, 2, 3, end |
|
