Question: ( 2 0 points ) An undirected connected graph G = ( V , E ) is resilient if it has no weakpoints. A vertex

(20 points) An undirected connected graph G =(V, E) is resilient if it has no weakpoints. A vertex v is a weakpoint, if deletion of this vertex from the graph (along with all its incident edges) the will make the graph disconnected. Give an O(V + E) time algorithm to detect if the graph is resilient. For example, a tree is not a resilient graph, but a cycle is.
