(Points nearest to each other) Listing 7.3 gives a program that finds two points in a two-dimensional space nearest to each other. Revise the program so that it finds two points in a three-dimensional space nearest to each other. Use a twodimensional array to represent the points. Test the program using the following points:

The formula for computing the distance between two points (x1, y1, z1) and (x2, y2, z2) is
