Samantha was hired to perform an internal security test of company XYZ. She quickly found that all networks are making use of switches instead of traditional hubs. This greatly limit her ability to perform network sniffing for information gathering. Which of the following techniques could she use use to gather information from the switched network or to disable some of the traffic isolation feature of the swtich?a. sniff in promiscuous mode b. ethernet zapping c. ARP spoofing d. TCP session hijacking

In this problem, we want to determine a set of states with the smallest total population that achieves an electoral college win. specifically, for each state i, for i = 1, 2, . . , n, let pi be its population and vi its electoral votes. all electoral votes of a state go a single candidate, and so the (overall) winning candidate is the one who receives at least v = b( p i vi)/2c + 1 electoral votes. our goal is to find the set of states s for which p i∈s pi is as small as possible subject to the constraint that p i∈s vi ≥ v . design a dynamic programming algorithm for this problem; prove its correctness; and analyze its time complexity.
