RE: Computation Contest #7 Results and Solution

I think in my case it grows exponentially because my algorithm doesn't stop when a certain level of precision is achieved, but it stops after doing n iterations.
So it depends on the input that is exponential. But I'm not sure.
I should modify the algorithm and find the exactly number of iteration and time needed to achieve 1,2,3,4,5,... decimal digits correct. And see if it changes.
