[...]

Possible, but that's not how I'd interpret it.  I'd assume that the
intent is to write a function to sort an array of integers using pointer
notation rather than using the [] operator.

This illustrates the importance of precise problem descriptions.  There
are too many things that "a pointer version of a sort() function" could
mean.
