1037. Valid Boomerang

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 == 3 - points[i].len
