Then we move to one of the neighbors of the present vertex and print its values. If there are no neighbors of the current vertex that have to be printed, we move to the previous vertex to see if all of their neighbors are printed. richard plummer

The only catch here is, unlike trees, graphs may contain cycles, so we may come to the same node again. To avoid processing a node more than once, we use a boolean visited array. For example, in the following graph, we start traversal from vertex 2.
