Question

What does the following code print?

val airports= sc.parallelize (Array(1L, ("SFO")), (2L, ("ORD")),(3L,("DFW"))))

val routes = sc.parallelize

(Array(edge(1L,2L,1800),Edge(2L,3L,800),Edge(3L,1L,1400)))

val nowhere ="nowhere"

valraph = Graph(airports,routes,nowhere)

graph.vertices.collect.foreach(printLn)

Option a) (2,ORD)

                (1,SFO)

                (3,DFW)

Option b)Edge(1,2,1800)

               Edge(2,3,800)

               Edge(3,1,1400)

Option c)(1,2,1800)

               (2,3,800)

               (3,1,1400)

Option d)Run time error
