Weights: A$-$D$->10,$ A$-$B $->13,$B$-$D$->20,$E$-$C $->22,$ B$-$F$>18,$ C$-$F $->30,$ B$-$C $->5.$ Perform a breadth$-$first traversal of the graph shown above, starting with vertex C$.$ Select the

smallest edge first when appropriate. In the space below, list the vertices in the order in which

they are visited.
