At this point, the smallest item is stored at the root of the heap. Replace it with the last item of the heap followed by reducing the size of heap by 1. Finally, heapify the root of tree. Repeat above steps while size of heap is greater than 1.

Rather than starting with a trivial heap and repeatedly adding leaves, Floyd's algorithm starts with the leaves, observing that they are trivial but valid heaps by themselves, and then adds parents… bubble stash ipa

"WebA heap can be implemented as an array by recording its elements in the top-down, left-to-right fashion. It is convenient to store the heap’s elements in positions 1 through n of such an array, leaving H [0] either unused or putting there a sentinel whose value is greater than every element in the heap. In such a representation, " - Heapsort top down
