The problem statement said nothing about whether the sort modified the
original array or not. Ada doesn't specify whether arrays are passed by
reference; if you want to do a sort in place and return the same array
then you'll use access types (pointers if you speak C) and work with
references to the array. I consider it an excellent feature of Ada that
there is no extra syntax for this, unlike C.
