template<class RandomAccessRange>
RandomAccessRange& push_heap(RandomAccessRange& rng);

template<class RandomAccessRange>
const RandomAccessRange& push_heap(const RandomAccessRange& rng);

template<class RandomAccessRange, class Compare>
RandomAccessRange& push_heap(RandomAccessRange& rng, Compare pred);

template<class RandomAccessRange, class Compare>
const RandomAccessRange& push_heap(const RandomAccessRange& rng, Compare pred);

Description

push_heap adds an element to a heap. It is assumed that begin(rng), prior(end(rng)) is already a heap and that the element to be added is *prior(end(rng)).

The ordering relationship is determined by using operator< in the non-predicate versions, and by evaluating pred in the predicate versions.

Definition

Defined in the header file boost/range/algorithm/heap_algorithm.hpp

Requirements

For the non-predicate versions:

For the predicate versions:

Precondition:
Complexity

Logarithmic. At most log(distance(rng)) comparisons.
