Consider a Graph class that stores the

graph using $an$ EdgeList data structure. When answering the following runtime questions,

give the most specific runtime bound you can: $if$ a BigTheta bound exists, give that,

otherwise give the tightest upper bound $(Big-O)$ you can.

$(a)(3$ points$)$ Derive the unqualified worst$-$case runtime $(in$ terms $of|V|$ and $|E|)to$

perform a $BFS$ search $on$ a Graph that $is$ implemented using $an$ EdgeList. Justify

your answer $inat$ most three sentences. Answers without justification

will not receive credit. Note:

$(b)(3$ points$)To$ perform a $BFS$ search $of$ the graph, $we$ may first compute the AdjacencyList and then searched the graph. What $is$ the total unqualified worst$-$case

runtime $(in$ terms $of|V|$ and $|E|)to$ compute the AdjacencyList and then perform

the $BFS$ search. Justify your answer $inat$ most three sentences. Answers

without justification will not receive credit.
