Description

Given an array of points on the X-Y plane points where points[i] = [xi, yi], return the area of the largest triangle that can be formed by any three different points. Answers within 10-5 of the actual answer will be accepted.

Example 1:

**Input:** points = [[0,0],[0,1],[1,0],[0,2],[2,0]]
**Output:** 2.00000
**Explanation:** The five points are shown in the above figure. The red triangle is the largest.

Example 2:

**Input:** points = [[1,0],[0,0],[0,1]]
**Output:** 0.50000

Constraints:

• 3 <= points.length <= 50

• -50 <= xi, yi <= 50

• All the given points are unique.
