The inverse of a map is a new map where the values of the original map become the keys of the new map and the keys become the values. For example, given the map {1:2, 3:4}, the inverse is the map {2:1, 4:3}. Given the map, d, create the inverse of d. Associate the new map with the variable inverse. You may assume that there are no duplicate values in d (that is no two keys in d map to the same value).

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).
