Problem 5. (Closest Point) Write a program that takes three floats z, y, and z from the command line, reads from standard input a sequence of coordinates (xi, /i, 2i), and writes the coordinates of the point closest to (x, y, 2). Recall that the square of the distance between (z y, z) and (zi y ,z) is (z x. + (y y)2 + (z )2. For efficiency, do not use either math sqrt() or the operator. 2.0 6.0 3.0 5.0 6.0 5.0 $ python3 closest.py 1.0 5.0 2.0 1.0 3.0 9.0 5.0 3.0 2.5 9.0 6.0 2.0 2.0 6.0 3.0 5.0 6.0 5.0 closest point(2.000000, 6.000000, 3.000000)
