WebNov 11, 2024 · The two main methods to store a graph in memory are adjacency matrix and adjacency list representation. These methods have different time and space … The simplest adjacency list needs a node data structure to store a vertex and a graph data structure to organize the nodes. We stay close to the basic definition of a graph - a collection of vertices and edges {V, E}. For simplicity, we use an unlabeled graph as opposed to a labeled one i.e. the vertices are identified … See more Finding the adjacent list is not quicker than the adjacency matrix because all the connected nodes must be first explored to find them. See more We use Java Collections to store the Array of Linked Lists. The type of LinkedList is determined by what data you want to store in it. For a labeled graph, you could store a dictionary instead of an Integer See more It is the same structure but by using the in-built list STL data structures of C++, we make the structure a bit cleaner.
