- Which of the statements are correct? (Select all that applies.) Group of answer choices A digraph is a graph whose edges are all directed. Digraphs can be applicable for detecting wash trade in financial market. Dijkstra's algorithm is based on the greedy method. Kruskal algorithm can be used to create a Minimum Spanning Tree. BFS runs in O(V+E) , where V is the number of vertices and E is the number of edges in the graph. DFS runs in O(V+E) as well.arrow_forwardThe below adjacency matrix M represents a directed graph. 0 1 1 M=|1 0 1 1 0 Select one: O True O Falsearrow_forwardOperations Research (OR)arrow_forward

Answer: here a 5 b () 3 1 d 4 C 2 6 earrow_forwardWhat is the best case, worst case time complexity for determining if a given directed edge exists in a graph. Assume the outgoing edges from each Vertex are stored in an adjacency list for that vertex. V is the total number of vertices in the graph, and E is the total number of outgoing edges in the graph, and you can find the vertex itself in constant time from a HashTable or HashMap ?
