Thanks a lot, Hunter! I was wondering how to put the numbers into a heap from an array, and now I know.

2:50 Isn't 2 actually the right child of 1? Doesn't the rule of floor(i/2) assume that indexes start at 1?

To delete the root, just do this:
1. save the old root
2. put the last element in the root slot and decrement the heapsize
3. call the heapify function on the root slot
