Problem 475. Is this group simply connected?
Given connectivity information about a graph, your job is to figure out if the graph is fully connected. You are given a list of vertex pairs that specify undirected connectivity (edges) among vertices. Vertex labels are always positive integers.
Example 1:
Input node_pairs = [ 8 9 8 3 ] Output tf is true
The three nodes of this graph are fully connected, since this graph could be drawn like so:
3--8--9
Example 2:
Input node_pairs = [ 1 2 2 3 1 4 3 4 5 6 ] Output tf is false
This graph could be drawn like so:
1--2 5--6 | | 4--3
There are two distinct subgraphs.

Maybe some tests with more than two distincts subgraphs.

Seems the problem became easier with R2015b.
