Dfs using recursion for graph

WebDepth-first search (DFS) is an algorithm for searching a graph or tree data structure. The algorithm starts at the root (top) node of a tree and goes as far as it can down a given branch (path), then backtracks until it finds an unexplored path, and then explores it. The algorithm does this until the entire graph has been explored. Many problems in computer … WebAug 18, 2024 · def recursive_dfs(graph, source,path = []): if source not in path: path.append(source) if source not in graph: # leaf node, backtrack return path for …
