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). WebJun 10, 2024 · Here, the concept of space and time complexity of algorithms comes into existence. Space and time complexity acts as a measurement scale for algorithms.
