  QUIZ 11:
  
  NASA's countdown to launch includes checkpoints where NASA engineers complete certain technical tasks.
  During the final minute, NASA has 6 tasks to complete:
  
  Orbiter transfers from ground to internal power (T-50 seconds)
  Ground launch sequencer is go for auto sequence start (T-31 seconds)
  Activate launch pad sound suppression system (T-16 seconds)
  Activate main engine hydrogen burnoff system (T-10 seconds)
  Main engine start (T-6 seconds)
  Solid rocket booster ignition and liftoff! (T-0 seconds)
  NOTE: "T-50 seconds" read as "T-minus 50 seconds".
  Directions:
  Write a while loop that counts down from 60 seconds and:
  
  If there's a task being completed, it prints out the task
  If there is no task being completed, it prints out the time as T-x seconds
  Use the task and time descriptions described above.

  Your Code:
  Your output should look like the following:
  
  T-60 seconds
  T-59 seconds
  T-58 seconds
  ...
  T-51 seconds
  Orbiter transfers from ground to internal power
  T-49 seconds
  ...
  T-3 seconds
  T-2 seconds
  T-1 seconds
  Solid rocket booster ignition and liftoff!
