In this code:
https://github.com/mostafa-saad/ArabicCompetitiveProgramming/blob/master/04%20Math/Computational_Geometry_12_Line_Sweep_2_Segments_Intersection.cpp
When I use the code, I use this case:
5
1 1 3 3
1 2 3 2
1 3 3 1
-1 -1 2 3
0 -2 1 4
It should give six intersections(although 4 different) , but it only gives five(3 different):
5 4
2 1
3 2
4 3
3 1

The ignored one should be '2 4'. I can just find the problem, but I don't know how to deal with it. Could you give me some advice?
