The Thought Process

When 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?

Solution

Browse to a post with a negative number, such as /post/-1.
