If there are items that are equal in the range, then the order of these items after the sort is not guaranteed; if this order is important, you should call the stable_sort function instead. If you want to preserve the input range and copy the sorted items into another range, you use the confusingly named partial_sort_copy function. This is not a partial sort. This function is passed iterators to the input range and iterators for the output range, ...
