What is an adjacency list in a graph?
In graph theory and computer science, an adjacency list is a collection of unordered lists that are used to represent a finite graph. Each unordered list within an adjacency list describes the set of neighbors of a particular vertex in the graph.

How do you write an adjacency matrix for a directed graph?
The adjacency matrix of a graph that has vertices P1,P2,…,Pn is the n × n matrix whose input (i,j) is the number of edges connecting Pi and Pj. The adjacency matrix of a digraph having vertices P1,P2,…,Pn is the n × n matrix whose input (i,j) is the number of directed edges from Pi to Pj.
Which of the following data structures are required to represent a graph using an adjacency list?
The simplest adjacency list needs a nodes data structure to store a vertex and a graphs data structure to organize the nodes. We stay close to the basic definition of a graph: a collection of vertices and edges {V, E}.
What is the adjacency matrix representation of a graph?
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the array indicate whether or not the pairs of vertices are adjacent on the graph. If the graph is undirected (that is, all its edges are bidirectional), then the adjacency matrix is symmetric.
When to use adjacency list?
In graph theory and computer science, an adjacency list is a collection of unordered lists that are used to represent a finite graph. Each list describes the set of neighbors of a vertex in the graph. This is one of several commonly used graph representations for use in computer programs.
What is the adjacent graph?
Adjacent (graph theory), two vertices that are the endpoints of an edge on a graph. Adjacent (music), a joint step to a note that follows in the scale.
What is the adjacent matrix?
Adjacency matrix. In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the array indicate whether or not the pairs of vertices are adjacent on the graph.
What is a vertex array?
Vertex arrays are graphs that show interconnected concepts or data. These charts can take a variety of forms, from traditional rows and columns of information to floating bubbles of conceptual relationships. For a small business owner, vertex arrays can help visualize the business as a whole,…
