WebThe depth-first search (DFS) algorithm is also used to search all the vertices of a graph or tree. Data structures such as a dictionary and lists can be used to build BFS in Python. The breadth-first search in a tree and a graph is nearly the same. The only difference is that the graph could have cycles, allowing us to return to the same node.
