Interesting... I found a pull request that claims a 65-130x faster
Python implementation with details here:
https://github.com/PlummersSoftwareLLC/Primes/pull/40
When I compared Python solution_1 to solution_2, solution_2 was about
200x faster (Ubuntu under VMWare on Windows).
The Python solution_2was just ahead of the C++ solution where I removed
vector<bool>. C++ using vector<bool> was about 45% faster.
I guess it shows how much difference a knowledge of language features
and picking the right structures etc. can make.
