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 idea you prove with bus routes, not with a slogan.

Assign directions to edges so that the directed graph remains acyclic order: meaning → BFS queue / DFS stack → one limit. Dumping ten features helps nobody.

Without Assign directions to edges so that the directed graph remains acyclic, a city map gets messy and bus routes is hard to trust.

Assign directions to edges so that the directed graph remains acyclic shows up in a city map. Name bus routes, not “a real-world scenario”.

If bus routes breaks under Assign directions to edges so that the directed graph remains acyclic, check no visited set → infinite loop first.

Place Assign directions to edges so that the directed graph remains acyclic next to nearby DSA work — BFS queue / DFS stack is the link.

Viva for Assign directions to edges so that the directed graph remains acyclic: what it is → BFS queue / DFS stack → the mistake (no visited set → infinite loop).

Exam tip

Say Assign directions to edges so that the directed graph remains acyclic in one breath, then BFS queue / DFS stack, then no visited set → infinite loop.

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).
