Prints numbers from 0 up to a given integer in a spiral

Goal:

Write some code that accepts an integer and prints the integers from 0 to that input integer in a spiral format.

For example, if I supplied 24 the output would be:

20 21 22 23 24
19  6  7  8  9
18  5  0  1 10
17  4  3  2 11
16 15 14 13 12

Notes:

• Implemented in JavaScript
• Takes integer input through a form
• Prints output to a <pre> element
• Watch the spiral grow outward: press "Start Printing Test"
• Enter a negative integer and the spiral goes in the opposite direction

spiral-printer's Issues

full spiral isn't printed when the given integer falls on the left side

For example: 4, 5, 16 - 19, 36 - 41, etc.
