An engineer is performing the IP subnet design for an organization and needs to find the best mask that should be used. The organization has been assigned the 172.16.44.0/22 network. They must have the addresses split up so they can be equally organized into16 subnets of at least 50 addresses. Which mask would best fit this requirement?
A) None
B) 255.255.255.240
C) 255.255.255.128
D) 255.255.255.192

In many applications, only a small percentage of the points in a given set p of n points are extreme. in such a case, the convex hull of p has less than n vertices. this can actually make our algorithm convexhull run faster than θ(nlogn). assume, for instance, that the expected number of extreme points in a random sample of p of size r is o(rα ), for some constant α < 1. (this is true when the set p has been created by picking points uniformly at random in a ball.) prove that under this condition, the running time of the algorithm is o(n).
