In this video I have discussed on Interview question asked in Nagarro interview for data engineers.
List the airlines that operate flights to all available destinations.
airlines_data = [
(1, "Airline A"),
(2, "Airline B"),
(3, "Airline C"),
]
flights_data = [
(1, 1, 101),
(2, 1, 102),
(3, 2, 101),
(4, 2, 103),
(5, 3, 101),
(6, 3, 102),
(7, 3, 103)
]
airlines_df = spark.createDataFrame(airlines_data, ["airline_id", "airline_name"])
flights_df = spark.createDataFrame(flights_data, ["flight_id", "airline_id", "destination_airport_id"])
