Use quotes:

for i in "${inputs[@]}"; do echo "$i"; done;
(1 3 4 8 6 2 7 0 5)
(2 8 1 0 4 3 7 6 5)

You need to use quotes. Say:

for i in "${inputs[@]}"; do echo $i; done

This would return:

(1 3 4 8 6 2 7 0 5)
(2 8 1 0 4 3 7 6 5)

Moreover, remove the ; after done unless it's the last line in your script!
