Representation of Graphs

Ways to Represent a Graph

The two most common ways to represent a graph are:

1. Adjacency Matrix
2. Adjacency List

Adjacency Matrix

The adjacency matrix is a two-dimensional matrix where each cell can contain a 0 or 1. If a cell contains 1, there exists an edge between the corresponding vertices e.g., $Matrix[0][1]=1$ shows that an edge exists between vertex 0 and 1. The row and column headings represent the vertices.
