Question

1- Compare the required space for graph representation in terms of edges and vertices using 

  1. a) list of edges, b) adjacency matrix, and adjacency list

2- Explain the Adjacency-list graph representation code

public class Graph
(
private final int V;
private Bag<Integer>[] adj;
public Graph(int V)
{
this.V - V;
adj - (Bag<Integer>[]) new Bag [V];
for (int v 0; v < V; V++)
adj [v] = new Bag<Integer>();
}
public void addEdge(int v, int w)
(
adj [v].add(w);
adj [w].add(v);
}
public Iterable<Integer> adj (int v)
{ return adj[v]; }
}
