    int end = n - 1;
 
    while (swapped)
    {
        // reset the swapped flag on entering
        // the loop, because it might be true from
        // a previous iteration.
        swapped = false;
 
        // loop from left to right same as
        // the bubble sort
        for (int i = start; i < end; ++i)

            }
        }
 
        // if nothing moved, then array is sorted.
        if (!swapped)
            break;
 
        // otherwise, reset the swapped flag so that it
        // can be used in the next stage
        swapped = false;
 
        // move the end point back by one, because
        // item at the end is in its rightful spot
