Representation of Graphs

Explore the fundamental ways to represent graphs using adjacency matrices and adjacency lists. Understand how these structures model edges and vertices in directed and undirected graphs, enabling you to effectively implement graph algorithms in Python.

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]=1Matrix[0][1]=1 ...
