Or yet another:

Here is a more declarative way:
public static class Array<T>

...algorithm's run-time.
In big-O() notation, constant factors are removed. Converting from one logarithm base to another involves multiplying by a constant factor.
So O(log N) is equivalent to O(log2 N) due to a constant factor.
However, if you can easily typeset log2 N in your answer, doing so is...
