WebFeb 18, 2024 · 1 Answer. In a strongly connected graph G, there must be a path from any node A to any (other) node B. To start, note that there is a path from B to A in the flipped graph G' if and only if there is a path from A to B in the original graph G. First we show that if G is strongly connected, the algorithm returns true.

WebCheck whether an undirected graph is a tree or not. An undirected graph is tree if it has following properties. There is no cycle. The graph is connected. Another way to understand this is to say that a tree is an undirected graph in which any two vertices are connected This problem has been solved! WebWe can use Depth–first search (DFS) to solve this problem. The idea is to find if any back-edge is present in the graph or not. A digraph is a DAG if there is no back-edge present in the graph. Recall that a back-edge is an edge from a vertex to one of its ancestors in the DFS tree. Fact: For an edge u —> v in a directed graph, an edge is a ...
