$[15$ pts$.]$: $[$The breadth$-$first search tree$]$ Solve Problem $7\mathrm{.}5$b from the Baase$$s textbook $($page

$376).$

Find the breath$-$first search tree and breath$-$first distances for the graph used in Example $7\mathrm{.}7$

$($see Figure $7\mathrm{.}28,$ above$)$ with G as the starting vertex under the assumption about the

adjacency$-$list order:

b$.$ Each adjacency list is in reverse alphabetical order
