Q2. In the divide and conquer algorithm for the closest pair problem, we are required to sort the
points accourding to their y-coordinates for the two subproblems generated when we divide the
points into two equal sized sets according to their x-coordinates. In the beginning all the points are
sorted according to their x- cordinates, list of which is maintained in P(x) and according
to y-coordinates, list of which is maintained in P(y). Write an O(n) algorithm to sort the subsets of
points during subsequent subproblems arising in solving the problem.
