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
trueThe three points are distinct and do not lie on the same straight line.
Example 2
Input
points = [[1,1],[2,2],[3,3]]Output
falseThe three points lie on the same straight line, so they do not form a boomerang.
Constraints
- points.length == 3
- points[i].length == 2
- 0 <= xi, yi <= 100
