Assign directions to edges so that the directed graph remains acyclic

Assign directions to edges so that the directed graph remains acyclic (alt) sits in a city map. Rohit’s job is bus routes. Write that first.

Keep Assign directions to edges so that the directed graph remains acyclic (alt) small. Rohit should finish bus routes in a few lines, not a 40-line dump.

Assign directions to edges so that the directed graph remains acyclic (alt) exists so Rohit can keep bus routes correct in a city map.

Use Assign directions to edges so that the directed graph remains acyclic (alt) when bus routes must stay clear. If a simpler DSA step works, use that instead.

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

After Assign directions to edges so that the directed graph remains acyclic (alt), Rohit should still remember no visited set → infinite loop.

One breath for Assign directions to edges so that the directed graph remains acyclic (alt), then bus routes, then no visited set → infinite loop. Sit down.

Exam tip

Board: bus routes. Dry-run Assign directions to edges so that the directed graph remains acyclic (alt). Name the trap: 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 (alt) — graphs are often stored as adjacency lists: vertex → list of (neighbor, weight).
