rotate
Syntax:
#include <algorithm> inline iterator rotate( iterator start, iterator middle, iterator end );
The rotate() algorithm moves the elements in the range [start,end) such that the middle element is now where start used to be, (middle+1) is now at (start+1), etc.
The return value of rotate() is an iterator to start + (end-middle).
rotate() runs in linear time.
