Solution
-
Breadth-first search is implemented using a queue: True. Breadth-first search (BFS) uses a queue data structure to keep track of the vertices that need to be explored.
-
Breadth-first search solves the single source shortest path problem in an unweighted graph: True. BFS can find the shortest path in an unweighted graph because it explores all vertices at the current depth before moving on to vertices at the next depth level.
-
Breadth-first search solves the single source shortest path problem in a weighted graph: False. BFS does not take into account the weights of the edges. It only considers the number of edges in the path. Therefore, it cannot solve the shortest path problem in a weighted graph.
-
Breadth-first search can be used in a directed or undirected graph: True. BFS can be used in both directed and undirected graphs. It explores all vertices reachable from the source vertex, regardless of whether the edges are directed or not.

The following six questions are about breadth first search and depth first search algorithms on a given graph. Consider an undirected graph 𝐺=(𝑉,𝐸)𝐺=(𝑉,𝐸) given below, where the set of vertices 𝑉={1, 2, 3, 4, 5}𝑉={1, 2, 3, 4, 5} and the set of edges 𝐸={(1, 2),(1, 3),(1, 4),(3, 2),(3, 5)}𝐸={(1, 2),(1, 3),(1, 4),(3, 2),(3, 5)}. We run BFS and DFS algorithms on this graph starting from the vertex 1 which is the initial vertex. Answer the following questions. 1 pointWhich are the three vertices that will be added to the BFS queue in the first step of the BFS algorithm? Does the order in which they are added matter? The three vertices will be 2, 3 and 4, their order will be exactly the same as the one given in this answer option. The three vertices will be 2, 3 and 4, their order does not matter. The three vertices will be 2, 3 and 5, their order will be exactly the same as the one given in this answer option. The three vertices will be 2, 3 and 5, their order does not matter.
