Leetcode Solutions
Checking for Collinearity Using Area of Triangle
- Extract the coordinates of the three points: (x1, y1), (x2, y2), and (x3, y3).
- Calculate the area of the triangle using the formula: Area = |(x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)) / 2|.
- If the area is zero, return
falseas the points are collinear. - If the area is non-zero, return
trueas the points form a boomerang.
