What would cause an algorithm to have O(log log n) complexitm>y m>?
... 16
16 / 2 = 8
8 / 2 = 4
4 / 2 = 2
2 / 2 = 1
This process takes 16 steps, m>and m> it's also the case that 65,536 = 216.
But, if we take the square root at each level, we get
√65,536 = 256
√256 = 16
√16 = 4
√4 = 2
Notice that it onlm>y m> takes four steps to get all the wam>y m> down to 2. Whm>y m> is this?...
