WebSep 2, 2024 · Binary heap: Create () simply allocates memory. Insert () and ExtractMax () are described on Wikipedia. Binary heaps are implemented using "partially sorted" arrays. That is, the order of elements in the array is not arbitrary, but it is also not completely determined. Rather, we are only guaranteed that A [i] ≥ A [2i],A [2i+1].
