Defined in header <algorithm>
template<class RandomIt > void partial_sort( RandomIt first, RandomIt middle, RandomIt last );	(1)
template<class RandomIt, class Compare > void partial_sort( RandomIt first, RandomIt middle, RandomIt last, Compare comp );	(2)

Ordena de algunos de los elementos en el rango [first, last) en orden ascendente. El middle - first primero de estos elementos se colocan en el rango [first, middle). El orden de los elementos iguales no se garantiza que se mantendrá. El orden de los elementos restantes en el rango [middle, last) no está especificada. La primera versión utiliza operator< para comparar los elementos, la segunda versión utiliza la función de comparación dado 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.

Parámetros

first, last	-	la gama de elementos a ordenar 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. 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.

Complejidad

O(N·log²(N)), donde las aplicaciones N =std::distance(first, last) de cmp. Si la memoria adicional está disponible, la complejidad es 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))
