Show hintHide hint
Think about the directionality and presence of cycles.
Question 2.
Define in-degree.
Show hintHide hint
Consider incoming connections to a task.
3Question 3.
Which of the following is true about DAGs?
- They have cycles
- They allow topological sorting
- They are undirected
Show hintHide hint
Recall the definitions of DAGs.
4Question 4.
True or False: A topological sort can be performed on any graph.
- True
- False
Show hintHide hint
Consider the requirement of the directed edges and cycles.
Question 5.
In a DAG representing course prerequisites, you have the following courses: A (Math), B (Physics), C (Programming), D (Data Structures). If Math is required for Physics, and Programming is necessary for Data Structures, what is a valid topological ordering of courses?
Show hintHide hint
Ensure prerequisites are ordered before dependent courses.
Question 6.
Create and explain a DAG for software development, identifying at least six tasks and their dependencies.
Show hintHide hint
Think about the typical software development lifecycle and dependencies.
