WebThis entails that there will be at most 2e recursive calls to dfs_helper. Furthermore, lines4and7, and the fact that marks are never reset, ensures that this function will be called no more than v times. Thus, there can be at most min(2e;v) recursive calls to dfs_helper. Each call to graph_free_neighborscosts O(1)in the adjacency list rep- WebDFS is widely-used as a part of many other algorithms that resolve graph-represented problems. From cycle searches, path finding, topological sorting, to finding articulation points and strongly connected components. The reason behind this widespread use of the DFS algorithm lies in its overall simplicity and easy recursive implementation.
