An adjacency list represents a graph as an array of linked list. In this tutorial, you will understand the working of adjacency list with working code in C, C++, Java, and Python.

Jul 23, 2025 · An adjacency list is a data structure used to represent a graph where each node in the graph stores a list of its neighboring vertices.

The following C++ program shows how to create an adjacency list for a graph. The program allows the user to input the number of vertices and edges, and then it displays the adjacency list.

That takes the vertex ('a' in this case) and adds it to the 'vertices' Linked List. Next, let us come to the next method that creates the Adjacency List.

What is the difference between an Adjacency List and an Adjacency Matrix? An Adjacency List stores only the existing edges in the graph, while an Adjacency Matrix is a 2D matrix where …

Here is a graph/social network where members Peter, Kevin, Jake, and Daniel are the four vertices of this social network. The edges between any two members corresponding to a …

Jul 23, 2025 · Each index of the array represents a vertex, and each element in its linked list represents the other vertices that form an edge with the vertex. In this article, we will learn how …

Jan 25, 2025 · This article explores three major ways to represent graphs—Adjacency List, Adjacency Matrix, and Edge List—along with their characteristics, applications, and …

Discover the ins and outs of creating an adjacency list in C++. This guide simplifies the concept with practical examples and handy tips for quick mastery.

We provide a simple (undirected) graph that has 5 vertices and 4 edges; each vertex is identified by a number. The adjacency list for the above graph would start with a linked list for vertices -- …
