4 cards from this section. Quick, good the night before a test.
What is the primary purpose of an adjacency matrix?
Think about how a table reflects relationships in a graph.
What does the space complexity O(V + E) pertain to?
Remember it combines both vertices and edges.
What is the space complexity of an adjacency matrix?
Consider how many entries the matrix needs.
True or False: An adjacency list can represent the graph more memory-efficiently for sparse graphs.
Think about space usage and how many connections we have.
Create an adjacency matrix and an adjacency list for a directed graph with 5 vertices and the following edges: (0 -> 1), (0 -> 2), (1 -> 3), (3 -> 4).
Focus on how directed edges affect your representation.
Explain a scenario where an adjacency list is preferred over an adjacency matrix for representing a graph.
Think about social dynamics in a graph.
