WebIn your routine, you implement is_prime (n) by checking if it's divisible by primes you've found before it. Whereas, I've reduce the complexity by checking to see n is divisible by the integers in 2..sqrt (n). i.e. I'm lazily checking with non-primes as well, but, I've optimize the search by only checking up to sqrt (n).
