/#+/;map{unshift@F,pop@F}1..$'.$;say@F


Explanation:

• -lF reads the input, removes the trailing newline, puts the remainder into the string $_, splits it up into characters, and puts that split into the array @F. • /#+/ finds #s in $_ and sets $ equal to the stuff before it and $' equal to the stuff after it. $'.$ is thus the number of times to rotate the array.
• Now for every element of the list from 1 to $'.$, rotate the array (pop the last element and unshift it onto the beginning).
• Then say all the elements of the rotated array.
