In some applications, such as in computer vision, an input set of two-dimensional points can be assumed to be given as pairs of integers, rather than arbitrary real numbers. Suppose, then, that you are given a set of n two-dimensional points such that each coordinate is in the range [0, 4n]. Show that you can construct a priority search tree for this set of points in O(n) time.
