1037. Valid Boomerang 
¶
Problem
Given an array points where points[i] = [xi, yi] represents a point on the X-Y plane, return true if these points are a boomerang.
A boomerang is a set of three points that are all distinct and not in a straight line.
Example 1:
Input: points = [[1,1],[2,3],[3,2]] Output: true
Example 2:
Input: points = [[1,1],[2,2],[3,3]] Output: false
Constraints:
points.length == 3points[i].length == 20 <= xi, yi <= 100
