(c) A group of friends wants to set up a message system so that anyone of them can communicate with any of the others either directly or indirectly or via others in the group from their houses A, B, C, D, E and F. The cost in dollar ($) of setting up the system between the pair of houses for which connections are possible are shown in Table 1. - - House B D EF A 11 B 11 6 5 6 4 6 3 7 D 5 3 8 6 7 F 85 Table 1: Costs between pair of houses. (i) Give the pseudocode for Kruskal's algorithm. (ii) Use Kruskal's algorithm to decide where they should make the links so that the total cost of setting the system will be as small as possible. (iii) Hence find the minimal cost
