Challenge Problems
Push your limits with advanced challenges
You are given a DAG representing tasks and their dependencies. Vertex 'A' has edges leading to 'B', 'C', and 'D'. If 'A' is removed, what will be the in degrees of 'B', 'C', and 'D'?
💡 Hint: Count how each vertex is affected by the removal of 'A'.
Demonstrate how the choice of vertices with in degree 0 affects the resulting topological order in a DAG you create.
💡 Hint: Draw the graph and label the in degrees before experimenting!
