DFS in Python: 2 Algorithms I wish I have learned earlier

WebIf your graph is implemented using adjacency lists, wherein each node maintains a list of all its adjacent edges, then, for each node, you could discover all its neighbors by traversing its adjacency list just once in linear time. For a directed graph, the sum of the sizes of the adjacency lists of all the nodes is E (total number of edges). WebJun 22, 2024 · A Computer Science portal for geeks.
