939. Minimum Area Rectangle 
¶
Problem
You are given an array of points in the X-Y plane points where points[i] = [xi, yi].
Return the minimum area of a rectangle formed from these points, with sides parallel to the X and Y axes. If there is not any such rectangle, return 0.
Example 1:
Input: points = [[1,1],[1,3],[3,1],[3,3],[2,2]] Output: 4
Example 2:
Input: points = [[1,1],[1,3],[3,1],[3,3],[4,1],[4,3]] Output: 2
Constraints:
1 <= points.length <= 500points[i].length == 20 <= xi, yi <= 4 * 104- All the given points are unique.
