# connected_components(+Graph, -ConnectedComponents)

Computes the connected components of graph
*Graph*
- a graph structure
*ConnectedComponents*
- a list of lists of node numbers

## Description

Computes the connected components of a (bidirected) graph. Each resulting
connected component is represented as an (unsorted) list of nodes.

This operation is only defined on bidirected graphs.
The runtime complexity is O(Nnodes + Nedges).

### Modes and Determinism
