When dealing with a graph it might be necessary to traverse the graph.Graph traversal is a systemic method to traverse the graph.Breadth first search is one of the most popular graph traversal algorithms that work very well for certain purposes.Today, I am going to introduce breadth first search in this post. How does breadth first search traverse? BFS is a graph traversal algorithm to visit vertices from one starting point in a certain way.How does it visit other nodes? It first visits its nearest neighbors and processes them before reaching any further nodes.And it marks nodes as it visits so READ MORE
