### The Thought ProcessWhen visiting the site, we can see the URL indexes the posts numerically in an ascending order. The homepage is `/post/0`, and subsequent posts are `/post/1`, `/post/2`, and so on.
We can browse to an arbitrary post by replacing the number in the URL with one of our choosing, such as `727`. What happens if we choose a number that comes before the first post... like a negative number?
### SolutionBrowse to a post with a negative number, such as `/post/-1`.
