This is the main function to test whether the algorithm is working well.

           {
    SegmentIntersection segment;
    Point first_point, second_point, third_point, forth_point;
 
    std::cin >> first_point.x >> first_point.y;
    std::cin >> second_point.x >> second_point.y;
    std::cin >> third_point.x >> third_point.y;
    std::cin >> forth_point.x >> forth_point.y;
 
    printf("%d", segment.intersect(first_point, second_point, third_point,
                                   forth_point));
    std::cout << std::endl;
