As the name suggests, Breadth first search (DFS) algorithm starts with the starting node, and then traverse each branch of the graph until we all the nodes are explored at least once. The algorithm explores all of the neighbor nodes at the present depth prior to moving on to the nodes at the next depth level. The data ...
