Consider the following four graph-theory problems. A. Given a graph G, determine the shortest path from vertex x to vertex y. B. Given a graph G, determine the longest path from vertex x to vertex y. C. Given a graph G, determine whether the graph has a Hamiltonian cycle - i.e., a cycle that passes through every vertex exactly once. D. Given a graph G, determine whether the graph has an Eulerian cycle - i.e., a cycle that passes through every edge exactly once. It turns out that exactly two of these problems can be answered quickly and efficiently, since the running time of the algorithm is polynomial (e.g. O(n³), O(n log n)) rather than exponential (e.g. O(2"), O(n!)) Determine which two problems can be solved in polynomial-time. Your answer will be two letters from the set [A, B, C, D].
