Defined in header <algorithm>
template<class RandomIt > RandomIt is_heap_until( RandomIt first, RandomIt last );	(1)	(desde C++11)
template<class RandomIt, class Compare > RandomIt is_heap_until( RandomIt first, RandomIt last, Compare comp );	(2)	(desde C++11)

Examina la [first, last) rango y encuentra la más amplia gama en principio first que es' montón. La primera versión de la función utiliza operator< para comparar los elementos, el segundo utiliza la función de comparación dado comp .

Original:

Examines the range [first, last) and finds the largest range beginning at first which is heap. The first version of the function uses operator< to compare the elements, the second uses the given comparison function comp.

Parámetros

first, last	-	la gama de elementos a examinar Original: the range of elements to examine 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 RandomAccessIterator.

Valor de retorno

El límite superior de la gama más grande de comienzo en first que es montón'. Es decir, el iterador it último para el que es amplia [first, it) montón' .

Original:

The upper bound of the largest range beginning at first which is heap. That is, the last iterator it for which range [first, it) is heap.

Ejemplo

#include <iostream>#include <algorithm>   int main(){std::vector<int> v {3, 1, 4, 1, 5, 9};   std::make_heap(v.begin(), v.end());   // probably mess up the heap v.push_back(2); v.push_back(6);   auto heap_end = std::is_heap_until(v.begin(), v.end());   std::cout<<"all of v: ";for(auto i : v)std::cout<< i <<' ';std::cout<<'\n';   std::cout<<"only heap: ";for(auto i = v.begin(); i != heap_end;++i)std::cout<<*i <<' ';std::cout<<'\n';}

Output:

all of v: 9 5 4 1 1 3 2 6 only heap: 9 5 4 1 1 3 2
