Queue

17.3 - Queue basic 3

Your task is now to create a mixtape song queue simulation program. Your program should accept those commands:

• enqueue
  Enqueue the song to the end of the song queue. It should create a new Song object and push it into the stack. It should also print "Added [song name] to the song queue." Note that the song name will always be one word only.

• wait
  Wait for duration amount. If any song ends during this period it should print out "Finished listening to [song name]." Multiple songs can end during a single wait command. Note that if there is still a song in the queue, the wait duration should be kept for the next wait (e.g. waiting for 10 and 20 should end a song with 30 duration.)

Sample input

enqueue LofiHipHopToRelaxAndStudy 30
wait 10
wait 25
enqueue Duwang 15
wait 10
enqueue JPop 5
wait 5
enqueue AllStar 10
enqueue KingCrimson 20
wait 30
