Write a program that takes three double command-line arguments x, y, and z, reads from standard input a sequence of point coordinates (xi, yi, zi), and prints the coordinates of the point closest to (x, y, z). Recall that the square of the distance between (x , y , z) and (xi , yi , zi ) is (x - xi )2 + (y  yi )2 + (z  zi )2. For efficiency, do not use Math.sqrt().
