Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is the in-degree of a vertex?
💡 Hint: Think about how many edges arrive at a vertex.
Question 2
Easy
Can a vertex with zero in-degree be processed first in topological sorting?
💡 Hint: If no tasks depend on it, it can go first!

Question 1
What is the primary goal of topological sorting?
- To find the shortest path
- To order vertices respecting dependencies
- To find cycles in a graph
💡 Hint: Think about the purpose of ordering in task management.
Question 2
True or False: A graph must be acyclic to perform a topological sort.

Challenge Problems
Push your limits with challenges.
Question 1
Design an algorithm to implement topological sorting with an input of edges in a directed graph. What are the expected outcomes?
💡 Hint: Think about how you can maintain order while processing.
Question 2
Consider a scenario with tasks {A, B, C, D} and dependencies {A->B, A->C, B->D}. What is a possible topological order?
💡 Hint: Every time you select a task, ensure no others depend on it that haven't been completed.
