06. Quiz: Countdown, Liftoff! (4-3)

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.
