I wouldn't discourage speculation on the price of the physical dwelling (i.e. the house). But land speculation is corrosive to society, and the way to fix that is with a land value tax.

Your reasoning is incorrect. Here is how I reason about it. Division by zero is undefined behavior. The compiler can assume that it will not happen. If the divisor is not zero, then the calculation has no side effects. The compiler may reor

B-tree deletions are quite complicated too, requiring stealing keys from either-side sibling or merging with either-side sibling. In practice, I find that a B-tree implementation is 2 to 3× the length of an AVL tree impl. I also fuzz-tested

I would not scoff at AVL trees. They are easy to prove correctness for, and admit a short implementation at ~100 lines. They're as short as AA trees, but AA trees are harder to prove with more cases. https://www.nayuki.io&#x
