Interface
|
||
|
|
========================================
|
||
|
|
.. sourcecode:: c++
|
||
|
|
|
||
|
|
template<typename RandomAccessIterator>
|
||
|
|
inline SPROUT_CONSTEXPR bool
|
||
|
|
is_heap(RandomAccessIterator first, RandomAccessIterator last);
|
||
|
|
|
||
|
|
template<typename RandomAccessIterator, typename Compare>
|
||
|
|
inline SPROUT_CONSTEXPR bool
|
||
|
|
is_heap(RandomAccessIterator first, RandomAccessIterator last, Compare comp);
|
||
|
|
|
||
|
|
Returns
|
||
|
|
========================================
|
||
|
|
|
||
|
|
| ``is_heap_until(first, last) == last``, ``is_heap_until(first, last, comp) == last``
|
||
|

|
|
Examples
|
||
|
|
========================================
|
||
|
|
.. sourcecode:: c++

|
|
#include <sprout/algorithm/is_heap.hpp>
|

|
||
|
|

|
||
|
|

|
||
|
|
|
||
|
|
Complexity
|
||
|
|
========================================
|
||
|
|
|
||
|
|
| Recursive function invocations in *O(logN)* (logarithmic) depth.
