Problem Explanation
Explanation
To find the area of the largest triangle formed by any three different points, we can iterate through all possible combinations of three points and calculate the area of the triangle formed by those points. The area of a triangle formed by three points (x1, y1), (x2, y2), and (x3, y3) can be calculated using the formula: area = 0.5 * |x1*(y2-y3) + x2*(y3-y1) + x3*(y1-y2)|. We iterate through all combinations of three points, calculate the area for each triangle, and keep track of the maximum area found.
Solution Code
class Solution {
public double largestTriangleArea(int[][] points) {
double maxArea = 0;
for (int i = 0; i < points.length; i++) {
for (int j = i + 1; j < points.length; j++) {
for (int k = j + 1; k < points.length; k++) {
double area = 0.5 * Math.abs(points[i][0] * (points[j][1] - points[k][1]) + points[j][0] * (points[k][1] - points[i][1]) + points[k][0] * (points[i][1] - points[j][1]));
maxArea = Math.max(maxArea, area);
}
}
}
return maxArea;
}
