Nice in-place solution, Werner, and a great RPN programming lesson with the % trick and optimal stack usage.
Each element is moved several times, so for large data set a more efficient algorithm may be used instead, like described in this HP Journal, p.34 right side about the HP-15C.
Maybe, Angel, was it the application you had in mind?
