push_heap function template — Adds a value to a heap

Synopsis

template<typename RandIter>
  void push_heap(RandIter first, RandIter last);
template<typename RandIter, typename Compare>
  void push_heap(RandIter first, RandIter last, Compare comp);

The push_heap function template adds the item at last - 1 to the heap in [first, last - 1), forming a new heap in the range [first, last).

The first form compares values using the < operator. The second form calls comp(*iter1, *iter2).
