Network Modeling Greedy Algorithm

"Telecommunication System Design You are designing a telecommunications system and need to connect a series of offices (shown as nodes) with fiber optic cable. You have information about which offices need to be connected (following diagram) and the cost for several possible network links. For the nodes shown below, please develop a minimum spanning tree using the greedy algorithm to find the optimal set of links. Specify which links are to be used and the resulting total cost to develop the network. "
