Depth first traversal in graph
WebMar 26, 2024 · Depth-first search (DFS) is yet another technique used to traverse a tree or a graph. DFS starts with a root node or a start node and then explores the adjacent nodes of the current node by going deeper into the graph or a tree. This means that in DFS the nodes are explored depth-wise until a node with no children is encountered. WebSep 9, 2024 · The depth first traversal of the graph above is in the order 1, 2, 4, 8, 7, 3, 6. A path is selected until no unvisited nodes remain reachable, then the traversal goes back to the last node that was visited that has unvisited adjacent nodes. A valid result of depth first search of the graph above is 1, 3, 6, 7, 8, 2, 5, 4. DFS Example 2
