In this tutorial, we’ll introduce this algorithm and focus on implementing it in both the recursive and non-recursive ways. First of all, we’ll explain how does the DFS algorithm work and see how does the recursive version look like.

It starts traversal through any one of its neighbour nodes and explores the farthest possible node in each path/branch and then starts Back-tracking.
WebFeb 20, 2024 · Both BFS and DFS are types of graph traversal algorithms, but they are different from each other. BFS or Breadth First Search starts from the top node in the graph and travels down until it reaches the root node. On the other hand, DFS or Depth First Search starts from the top node and follows a path to reaches the end node of the path.
