Counting More Rectangles
Each quadrilateral is described in four lines. Each line contains a pair of integers that describes a point \((x,y)\). Note that the points are not necessarily in clockwise / anticlockwise order.
Details and Assumptions:
- It is guaranteed that for a quadrilateral no points will be in the same spot.
- \(1\leq (x_i,y_i) \leq 4\)
This is an extension of this problem.
