Problem 3. In the class, you learned how to check if a graph is bipartite or not. In this problem, we assume the given graph G = (V, E) is not bipartite. Design an O(n+m)-time algorithm that outputs an odd cycle in G. Problem 3. In the class, you learned how to check if a graph is bipartite or not.
