Depth First Search Tutorials & Notes Algorithms

WebNov 23, 2024 · Depth first traversal is a graph traversal algorithm in which we start from a vertex of a graph and print its value. 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. WebGiven a graph, we can use the O(V+E) DFS (Depth-First Search) or BFS (Breadth-First Search) algorithm to traverse the graph and explore the features/properties of the … WebDFS of Graph.
