L'ordre des lments restants dans la gamme [middle, last) n'est pas spcifi. La premire version utilise operator< de comparer les lments, la deuxime version utilise la fonction de comparaison donne comp .Original:
Sorts some of the elements in the range
[first, last) in ascending order. The first middle - first of these elements are placed in the range [first, middle). The order of equal elements is not guaranteed to be preserved. The order of the remaining elements in the range [middle, last) is unspecified. The first version uses operator< to compare the elements, the second version uses the given comparison function comp.The text has been machine-translated via Google Translate.
