A helper algorithm for rotate() . If n is positive, rotates the container to the right by n positions; otherwise, rotates the container c to the left by n positions.

Declaration


  #include <ospace/helper/helpalgo.h>

template< class Container >
void os_rotate( Container& c, int n )

Example <ospace/helper/examples/orotate0.cpp>


    #include <iostream>
#include <vector>
#include <ospace/helper.h>

int numbers[ 6 ] = { 0, 1, 2, 3, 4, 5 };

void
main()
  {
  vector< int > v( numbers, numbers + 6 );

  os_rotate( v, 3 );

  for ( vector< int >::iterator i = v.begin(); i != v.end(); ++i )
    cout << *i << ` `;
  cout << "\n";
