Question
In Breadth First Search we examine _____.a)All of its childrens and then examine the root nodeb)The neighbors and then the root nodec)The root node and then traverse the neighborsd)The starting node and then go deeper and deeper.
Solution
The correct answer is c) The root node and then traverse the neighbors.
Here's the step by step process of Breadth First Search:
- Start by examining the root node (or any arbitrary node in case of a graph).
- Then, traverse its neighbors that are unvisited.
- Mark the current node as visited and enqueue all its unvisited neighbors.
- If the queue is not empty, dequeue the next node and go back to step 2.
- If the queue is empty, then every node in the tree/graph has been visited, and the algorithm ends.
This process continues until all the nodes in the tree or graph have been visited.

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.
