you are given a set of N points e.g ((x1,y1),(x2,y2),(x3,y3)...or (3,6),(2,5),(4,1)..) on a plane . Find the pair of points that are closest to each other. all these given points
are on X-axis and on Y-axis according to that you have to calculate the closest points using given co-ordinates.

Thanks in Advance.
