Ordina gli elementi della gamma
[first, last)
in ordine crescente. L'ordine degli elementi uguali è garantito per essere preservato. La prima versione utilizza operator< di confrontare gli elementi, la seconda versione utilizza la funzione di confronto dato comp
.Original:
Sorts the elements in the range
[first, last)
in ascending order. The order of equal elements is guaranteed to be preserved. The first version uses operator< to compare the elements, the second version uses the given comparison function comp

first, last | - | la gamma di elementi da ordinare Original: the range of elements to sort The text has been machine-translated via Google Translate. You can help to correct and verify the translation. Click here for instructions. |
comp | - | comparison function which returns true if the first argument is less than the second. The signature of the comparison function should be equivalent to the following: bool cmp(const Type1 &a, const Type2 &b); The signature does not need to have const&, but the function must not modify the objects passed to it. |

[modifica]Note
Questa funzione tenta di allocare un buffer temporaneo di dimensioni pari alla sequenza da ordinare, in genere chiamando std::get_temporary_buffer. Se l'allocazione non riesce, l'algoritmo meno efficiente è scelto.
Original:
This function attempts to allocate a temporary buffer equal in size to the sequence to be sorted, typically by calling std::get_temporary_buffer. If the allocation fails, the less efficient algorithm is chosen.
