They can be checked by the following code: The given Directed Graph is weakly connected, not strongly connected. We can use isEulerian() to first check whether there is an Eulerian Trail or Circuit in the given graph. Kosarajus algorithm for strongly connected components. where g is a Directed Graph. Here the edges will be directed edges, and each edge will be connected with order pair of vertices.
