`point`

holds the x coordinate of some points on x-axis in a plane, which are
all integers.
Write a query to find the shortest distance between two points in these points.

| x | |-----| | -1 | | 0 | | 2 |

The shortest distance is '1' obviously, which is from point '-1' to '0'. So the output is as below:

| shortest| |---------| | 1 |
