WebMar 19, 2024 · The sum of the sizes of the adjacency lists of all nodes in a directed graph is E. Thus, for a directed graph, the time complexity is O (V) + O (E) = O (V + E). In an undirected graph, each edge appears twice. Once at either end of the adjacency list for the edge. Thus, in this case, the time complexity is O (V) + O (2E) ~ O (V + E). http://duoduokou.com/algorithm/66087866601616351874.html

Web30. The time complexity for DFS is O (n + m). We get this complexity considering the fact that we are visiting each node only once and in the case of a tree (no cycles) we are crossing all the edges once. For example, if the start node is u, and the end node is v, we are thinking at the worst-case scenario when v will be the last visited node.
