Definition: A directed graph is strongly connected if there is a path from a to b and a path from b to a whenever a and b are vertices in the graph Example: G is strongly connected because there is a path between any two vertices in the directed graph Hence, G is also weakly connected

What is a strongly connected graph give an example?
Definitions. A directed graph is called strongly connected if there is a path in each direction between each pair of vertices of the graph. That is, a path exists from the first vertex in the pair to the second, and another path exists from the second vertex to the first.What is an example for strongly connected components?
For example: Pop vertex-0 from the stack. Starting from vertex-0, traverse through its child vertices (vertex-0, vertex-1, vertex-2, vertex-3 in sequence) and mark them as visited. The child of vertex-3 is already visited, so these visited vertices form one strongly connected component.How do you check if a graph is strongly connected or not?
If there is a path connecting each pair of the graph's vertices in each direction, a directed graph is said to be strongly connected. The first vertex in the pair has a path leading to the second, and the second vertex has a path leading to the first.- Definition: A directed graph that has a path from each vertex to every other vertex. Formal Definition: A directed graph D=(V, E) such that for all pairs of vertices u, v ? V, there is a path from u to v and from v to u.
