What would cause an algorithm to have O(log log n) complexity?
... n) times before you've reduced the number down to some constant (say, 2).
Now, let's do some math to make this rigorous. Le'ts rewrite the above sequence in terms of powers of two:
√65,536 = √216 = (216)1/2 = 28 = 256
√256 = √28 = (28)1/2 = 24 = 16
√16 = √24 = (24)1/2 = 22 = 4
√4 = ...

Why covariance and contravariance do not support value type
...hout any change in representation; the native code itself doesn't need to know what you're doing with the values at all, so long as the infrastructure has guaranteed that it will definitely be valid.
