What would cause an algorithm to have O(log log n) complexity?
...of a problem that yields runtimes of the form O(log log n). Instead of dividing the input in half at each layer, what happens if we take the square root of the size at each layer?
For example, let's take the number 65,536. How many times do we have to divide this by 2 until we get down to 1? If w...

}
};
