(Use the following information for questions 6 & 7) Seven computers {Co, C2, ....C6} are linked by a network, and each link has a main- tenance cost. The graph below shows how the computers are linked. Each node represents a computer, each edge represents a link between a pair of computers, and weights on the edges represent the maintenance cost (in hundreds of rupees). The goal is to pick a subset of links such that the total maintenance cost is minimum and the computers remain connected through the chosen links. 2 7 C C2 4 8 1 4 3 2 C4 Cs 6 5 6) What is the total maintenance cost (in hundreds of rupees) of the optimum subset of links? 1 point 7) Find the number of different ways of choosing an optimum subset of links for the given graph. 1 point
