What are the different types of graph representations?

There are several types of graph representations, including adjacency matrix, adjacency list, and edge list. Each has its own advantages.

Can you explain the adjacency matrix?

An adjacency matrix is a square matrix used to represent a finite graph. The elements indicate whether pairs of vertices are adjacent or not.

What about the adjacency list?

An adjacency list represents a graph as a collection of lists. Each list corresponds to a vertex and contains a list of its adjacent vertices.

When should I use an edge list?

An edge list is useful for sparse graphs and when you need to quickly iterate over edges. It's simple and efficient for certain operations.
