Write a function that interleaves two sounds. It starts with 2 seconds of the first sound and then 2 seconds of the second sound. Then it continues with the next 2 seconds of the first sound and the next 2 seconds of the second sound and so on until both sounds have been fully copied to the target sound.

For this answer, one cannot assume the two sounds will be the same length, or that they’ll go evenly into 2 second chunks, therefore it’s necessary to check whether one sound has already been “used up” in order to avoid a run time error.
