C++ push heap
WebThe push_heap () algorithm is used to add a new element to the heap. First, a new element for the heap is added to the end of a range. The push_heap () algorithm assumes that the range [start, finish - 1) is a valid heap. Then it properly positions the element in the location finish - 1 into its proper position in the heap, resulting in a heap ...
