The security director wants to connect the security video camera to the main control site of the five potential sites of interference

The security director wants to connect the security video camera to the main control site of the five potential sites of interference. Typically, cables will only run from each location to the main control site. However, because of the potentially explosive environment, cables must run in special ducts that are constantly cleaned. These lines are very expensive but large enough to handle five cables (the maximum that may be required). Use the tree minimal-spanning technique to find the minimum route distance for the channel between the locations listed in the network below. (Note that it makes no difference which is the primary control site.)
