Identify Strongly Connected Components
The strongly connected components in a directed graph are identified and returned as a list.

Tarjan's algorithm is used to determine all strongly connected components of a directed graph.
A list whose length is the number of strongly connected components in
g. Each element of the list is a vector of the node labels for
the nodes in that component.
