WebSep 9, 2024 · DFS Example 1. DFS. 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. WebFeb 20, 2024 · Complexity Of Depth-First Search Algorithm.
