WebJul 19, 2024 · DFS is a search algorithm that is generally used to traverse graphs. DFS can be implemented with recursion to do the traversal or implemented iteratively with a stack. WebTime & Space Complexity. The running time complexity of the DFS algorithm in java is O(V+E) where V is the number of nodes in the graph, and E is the number of edges. Since the algorithm requires a stack for storing the nodes that need to be traversed at any point in time, the space complexity is the maximum size of the stack at any point of time.
