Dfs python implementation
WebThe applications of using the DFS algorithm are given as follows -. DFS algorithm can be used to implement the topological sorting. It can be used to find the paths between two vertices. It can also be used to detect cycles in the graph. DFS algorithm is also used for one solution puzzles. DFS is used to determine if a graph is bipartite or not. WebNov 23, 2024 · Implementation of Depth first traversal in Python. As we have discussed the general idea for depth first traversal of a graph and observed how the algorithm works using the python program, we can implement the depth first traversal algorithm as follows.
