Depth First Search (DFS) in Python - Scaler Topics

WebApplications of DFS in Python. Topological sorting, scheduling problems, cycle detection in graphs, and solving puzzles with just one solution, such as a maze or a sudoku puzzle, all use depth-first search. Other uses involve network analysis, such as detecting if a graph is bipartite. DFS is also used as a subroutine in graph theory matching ... 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.
