Given a 2D plane, list of lines parallel to X-axis or Y-axis and list of rectangles (perimeter lines are parallel to either X-axis or Y-axis). Find the number of intersection points where these lines cut the rectangles.

For Example:-

We have been given Y coordinates for lines parallel X-axis -> 1, 2, 4, 19
and X coordinates for lines parallel to Y-axis -> 2, 5, 9

and there's 1 rectangle, given bottom left and top right coordinates as :-

Rectangle 1 -> ((1,3), (3,6))

Total number of intersection points are :- 4
