Challenge Problems
Push your limits with challenges.
Question 1
Consider a directed graph represented by an adjacency list. How many different edges can the graph contain if you have 'n' vertices? Provide a general formula and an example.
💡 Hint: Think about how many unique connections can exist.
Question 2
Given a sparse graph represented using an adjacency list, describe the impact on time complexity when attempting to find all neighbors of a node versus using a dense graph with an adjacency matrix.
💡 Hint: Consider how many edges relative to nodes influence the retrieval processes.
