Given two vectors (or arrays or lists) v1 = (x1, x2, xn) and v2 = (y1, y2, yn), their scalar product is v1 × v2, given by v1 × v2 = (x1* y1, x2 * y2, xn * yn). one way to represent it in oz is consider the vectors as lists and the scalar product × as the tuple operator #. write an oz program that does the scalar product of any two vectors. for example, scalarproduct [4 5 6]#[1 2 3] would have to return 32.

1. you have a small business that is divided into 3 departments: accounting, sales, and administration. these departments have the following number of devices (computers, printers, etc.): accounting-31, sales-28, and administration-13. using a class c private network, subnet the network so that each department will have their own subnet. you must show/explain how you arrived at your conclusion and also show the following: all available device addresses for each department, the broadcast address for each department, and the network address for each department. also, determine how many "wasted" (not usable) addresses resulted from your subnetting (enumerate them).
