Question: Problem 5 . A vertex v in a connected undirected graph G is called a cut vertex if the subgraph G - v ( obtained

Problem 5. A vertex v in a connected undirected graph G is called a cut vertex if the subgraph G-v (obtained by removing v from G ) is disconnected.
Describe an algorithm that identifies every cut vertex in a given undirected graph in O(V+E) time.
Prove the correctness of your algorithms and analyze their running time (or any other efficiency measure asked in the question). Solve the question in detail and show each and every step.
