C program to implement Depth First SearchDFS C program to implement Depth First SearchDFS. Depth First Search is an algorithm used to search the Tree or Graph. DFS search starts from root node then traversal into left child node and continues, if item found it stops other wise it continues. The advantage of DFS is it requires less memory compare to Breadth First SearchBFS. Read more about C Programming Language. You can use all the programs on www.

Breadth First Traversal or Search for a graph is similar to Breadth First Traversal of a tree See method 2 of this post. 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 simplicity, it is assumed that all vertices are reachable from the starting vertex. For example, in the following graph, we start traversal from vertex 2. When we come to vertex 0, we look for all adjacent vertices of it. If we dont mark visited vertices, then 2 will be processed again and it will become a non terminating process. A Breadth First Traversal of the following graph is 2, 0, 3, 1.

Illustration Note that the above code traverses only the vertices reachable from a given source vertex. All the vertices may not be reachable from a given vertex example Disconnected graph. To print all the vertices, we can modify the BFS function to do traversal starting from all nodes one by one Like the DFS modified version. Time Complexity OVE where V is number of vertices in the graph and E is number of edges in the graph.
