Assign directions to edges so that the directed graph remains acyclic — DSA Technical Interview Questions & Answers

Assign directions to edges so that the directed graph remains acyclic

Assign directions to edges so that the directed graph remains acyclic

  • Assign directions to edges so that the directed graph remains acyclic is a DSA topic. In plain words you use it for bus routes in a city map. Don’t start with a slogan — start with that picture.
  • Smallest example: BFS queue / DFS stack. Type it, run it, and say what you see. If you can do that from memory, you know Assign directions to edges so that the directed graph remains acyclic.
  • From the example next to this theory: Assign directions to edges so that the directed graph remains acyclic — graphs are often stored as adjacency lists: vertex → list of (neighbor, weight).
  • Trap: no visited set → infinite loop. Fix that before you talk about advanced DSA.
  • Viva: what is Assign directions to edges so that the directed graph remains acyclic? Then show BFS queue / DFS stack. Then name the trap.

Technical Interview Tip: What is Assign directions to edges so that the directed graph remains acyclic? Show this: BFS queue / DFS stack. Trap: no visited set → infinite loop.

Code Examples for Assign directions to edges so that the directed graph remains acyclic

Assign directions to edges so that the directed graph remains acyclic — working example

# adjacency list
graph = {
    "A": [("B", 2), ("C", 5)],
    "B": [("A", 2), ("C", 1)],
    "C": [("A", 5), ("B", 1)],
}
for u, edges in graph.items():
    print(u, "->", edges)

Assign directions to edges so that the directed graph remains acyclic — graphs are often stored as adjacency lists: vertex → list of (neighbor, weight).
