Shortest Distance in a Line LeetCode Solution

Problem Statement

Table 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.

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

Note: Every point is unique, which means there is no duplicates in the table point.
