Using an array as a heap is also easier with 1-based indexing: base-element := some-vector[i]; left-child := some-vector[i * 2]; right-child := some-vect

Using an array as a heap is also easier with 1-based indexing: base-element := some-vector[i]; left-child := some-vector[i * 2]; right-child := some-vector[i * 2 + 1]; where the root element is `some-vector[1]'.
