Create a public class GraphAnalysis that provides a single static method named isUndirected. isUndirected accepts an UnweightedGraph from cs1.graphs and should return true if the graph is undirected and false otherwise. If the passed graph is null, throw an IllegalArgumentException. Each node in the graph has a set of neighbors that you can retrieve representing links from that node to other nodes. If the graph is undirected, if there is a link from A to B ther there is also a link from B to A. So if B is a neighbor of A, then A should also be a neighbor of B. Note that you do not need to solve this problem recursively, since there is a concise iterative solution. For reference, csl.graphs.UnweightedGraph has the following public properties: 1 public class UnweightedGraph { public Set getNodes (); // returns all node in the graph 3 } And csl.graphs.GraphNode has the following public properties: 1 public class GraphNode { public Object getValue(); // returns the value public Set getNeighbors (); // returns the neighbors of this node 2 3

Create a public class GraphAnalysis that provides a single static method named isUndirected. isUndirected accepts an UnweightedGraph<?> from cs1.graphs and should return true if the graph is undirected and false otherwise. If the passed graph is null, throw an IllegalArgumentException. Each node in the graph has a set of neighbors that you can retrieve representing links from that node to other nodes. If the graph is undirected, if there is a link from A to B then there is also a link from B to A. So if B is a neighbor of A, then A should also be a neighbor of B. Note that you do not need to solve this problem recursively, since there is a concise iterative solution. For reference, csl.graphs.UnweightedGraph has the following public properties: 1 public class UnweightedGraph { public Set<GraphNode> getNodes (); // returns all node in the graph 3 } And csl.graphs.GraphNode has the following public properties: 1 public class GraphNode { public Object getValue(); // returns the value public Set<GraphNode> getNeighbors (); // returns the neighbors of this node 2 4 }
