points on a 2D plane where
points[i] = [xi, yi], Return the widest vertical area between two points such that no points are inside the area.
A vertical area is an area of fixed-width extending infinitely along the y-axis (i.e., infinite height). The widest vertical area is the one with the maximum width.
Note that points on the edge of a vertical area are not considered included in the area.
Input: points = [[8,7],[9,9],[7,4],[9,7]] Output: 1 Explanation: Both the red and the blue area are optimal.
Input: points = [[3,1],[9,0],[1,0],[1,4],[5,3],[8,8]] Output: 3
n == points.length
2 <= n <= 105
points[i].length == 2
0 <= xi, yi <= 109
