Points inside Rectangles
Let's say that we have n Rectangles with known coordinates and m Points with known coordinates.
How to count the number of points that lie inside each Rectangle given that the coordinates are integers (>= 0, <= 106) and n & m <= 106.
Surely, the complexity of O(n*m) is not desirable!
I think of Segment Tree but don't know how and if it's better or not!
May you help me, please?
