Question: Which of the following problems can be solved using BFS?

Options:

Correct Answer: Finding connected components in a graph

Solution:

BFS can be used to find connected components in an unweighted graph by exploring all reachable vertices from a starting vertex.

Which of the following problems can be solved using BFS?

Step 1: Understand what BFS (Breadth-First Search) is. It is a method for exploring nodes in a graph level by level.
Step 2: Identify the type of graph you are working with. BFS is particularly useful for unweighted graphs.
Step 3: Choose a starting vertex (node) in the graph from which you want to explore.
Step 4: Use BFS to explore all the vertices that can be reached from the starting vertex. This means visiting all neighboring nodes first before moving deeper.
Step 5: Keep track of the vertices you have visited to avoid visiting the same vertex multiple times.
Step 6: Once you have visited all reachable vertices, you will have identified all the connected components that can be reached from the starting vertex.
