In computer science, graph traversal (also known as graph search) refers to the process of visiting (checking and/or updating) each vertex in a graph. Such traversals are classified by the order in which the vertices are visited. Tree traversal is a special case of graph traversal. WebMar 10, 2024 · Method 1 (Simple) One straight forward solution is to do a BFS traversal for every node present in the set and then find all the reachable nodes. Assume that we need to find reachable nodes for n nodes, the time complexity for this solution would be O (n* (V+E)) where V is number of nodes in the graph and E is number of edges in the graph.
