ah, got it; thanks.

interesting, wouldn't the same problem occur changing instructions to input as I have done above? because doing so passes the submission test.

test some random arrays
> [ 6, 11, 3, 8, 5, 2, 7, 1, 4, 10, 9 ]
Expected: liftoff! 11 10 9 8 7 6 5 4 3 2 1 liftoff!, instead got: 11 10 9 8 7 6 5 4 3 2 1 liftoff!

why is "liftoff!" expected before the countdown has begun?

test case 3 does not fit instructions, why does the expected string begin with "liftoff!"
