WebMar 18, 2012 · If built from the bottom up, insertion (heapify) can be much less than O (log (n)). The process is as follows: ( Step 1 ) The first n/2 elements go on the bottom row of the heap. h=0, so heapify is not needed. ( Step 2 ) The next n/2 2 elements go on the row 1 up from the bottom. h=1, heapify filters 1 level down.
