What are some common graph representation techniques in C++?

In C++, common graph representation techniques include adjacency matrix, adjacency list, and edge list. Would you like to know more about any specific technique?

Can you explain the adjacency list representation?

Sure! An adjacency list represents a graph as an array of lists. Each index in the array corresponds to a vertex, and the list at that index contains all the vertices adjacent to it. This is memory efficient for sparse graphs.

What are the advantages of using an adjacency list?

The advantages include lower memory usage for sparse graphs, faster iteration over neighbors, and easier implementation of graph algorithms.

Are there any disadvantages?

Yes, the main disadvantage is that it can be slower for dense graphs compared to an adjacency matrix, especially for checking the existence of an edge.
