Flashcard drill
3 cards from this lesson. Good the night before a test.
Try these first
- 1.
Define a Directed Acyclic Graph (DAG).
Hint
Think about the term 'acyclic'.
- 2.
What is topological sorting?
Hint
Consider the order of tasks with dependencies.
- 3.
What defines a Directed Acyclic Graph?
- It has loops
- It has directed edges
- It is undirected
Hint
Focus on the structure of the graph.
- 4.
True or False: Every DAG can be topologically sorted.
- True
- False
Hint
Think about dependency structures.
- 5.
Consider a project with multiple tasks where some depend on previous completion. Create a DAG of this project and compute the longest path.
Hint
Focus on where the longest chains tend to originate.
- 6.
If adding a task modifies existing dependencies, recalibrate the longest path. What challenges might this present and how would you address them?
Hint
Consider how changes ripple through the project dependencies.
