Nice work. You hit the learning goals here, but struggled a bit in Big-O. Take a look at my comments and let me know any questions you have.

Since you don't allocate more data as n increases in size, this is O(1) for space complexity.

We're not running nested loops here. instead the loop cuts the number of items to look at in half each iteration. So this is O(log n).
