public class NonrecursiveDFS extends Object
NonrecursiveDFSclass represents a data type for finding the vertices connected to a source vertex s in the undirected graph.
This implementation uses a nonrecursive version of depth-first search
with an explicit stack.
DepthFirstSearch for the classic recursive version.
The constructor takes time proportional to V + E,
where V is the number of vertices and E is the number of edges.
It uses extra space (not including the graph) proportional to V.
