Here is a directed graph. In the graph, (u, v) means that there is an edge from node u to node v. The graph contains nodes: 1, 2, 3, 4, 5, 6, 7, 8, 9,... | Yes | graph_is_strongly_connected |
The task is to determine the number of strongly connected components in a directed graph.
A strongly connected component is a maximal subgraph where every node is reachable from every other node.

The task is to determine if the graph is bipartite.
A bipartite graph is a graph whose nodes can be divided into two disjoint sets such that no two graph vertices within the same set are adjacent.

The task is to determine the depth-first search (DFS) traversal order given a starting node.
Here is an undirected graph. In the graph, (u, v) means that node u and node v are connected. The graph contains nodes: 1, 2, 3, 4, 5, and 6. The graph contains edges: (1, 4), (1, 2), (3, 4), (3, 6), (5, 6).

The task is to find all bridges of a graph.
A bridge is an edge in a graph whose removal increases the number of connected components.
Here is an undirected graph. In the graph, (u, v) means that node u and node v are connected. The graph contains nodes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16. The g... | [(1,7),(1,15),(2,3),(7,12),(13,14)] | graph_bridges |
