WebJun 27, 2014 · For purposes of building the heap in this way, it doesn't matter if the array indexes start at 0 or 1. If the array is 0-based, then you end up making one extra call to downheap, but that doesn't do anything because the node you're trying to move down is already a leaf node. So it's slightly inefficient (one extra call to downheap), but not ...
