Problem: I have coordinates of of two side of the rectangles-
Suppose I have coordinates of 5000 boxes. Like this-
These coordinates subdivide an unit squre like this -
( x1, y1) ( x2, y2)
(0.0000,0.4175) (0.3412,0.6553) ...etc
I want to calculate the number of nearest rectangles for each of the boxes using c++.
For rectangle# 7 the nearest boxes are- 4,1,6 and 2
(If they share only corner they are not consider as nearest boxes, So rectangle 5 & 3 are not nearest of rectangle 7)
Can anyone help me how can I write the algorithm for this problem?
