Sortiert die Elemente im Bereich [first, last) in aufsteigender Reihenfolge. Die Reihenfolge der gleiche Elemente garantiert erhalten. Die erste Version verwendet operator< um die Elemente zu vergleichen, verwendet die zweite Version des gegebenen Vergleichsfunktion 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.

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.
The types Type1 and Type2 must be such that an object of type RandomIt can be dereferenced and then implicitly converted to both of them. ​

Type requirements
-
RandomIt must meet the requirements of ValueSwappable and RandomAccessIterator.
-
The type of dereferenced RandomIt must meet the requirements of MoveAssignable and MoveConstructible.

[Bearbeiten] Komplexität

O(N·log2(N)), wo N = std::distance(first, last) Anwendungen cmp. Wenn zusätzlicher Speicher verfügbar ist, dann ist die Komplexität O(N·log(N) .
Original:
O(N·log2(N)), where N = std::distance(first, last) applications of cmp. If additional memory is available, then the complexity is O(N·log(N).

[Bearbeiten] Notes

Diese Funktion wird versucht, einen temporären Puffer die gleiche Größe wie die Sequenz, die sortiert, typischerweise durch Aufrufen std::get_temporary_buffer aufzuteilen. Wenn die Zuweisung fehlschlägt, wird die weniger effizienten Algorithmus gewählt .
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.
