I once went to a company interview, encountered such a topic: ask for the number of primes within 1000 how many? Use multithreading to achieve, and give time to consume. I thought for a while and didn't come up with a multi-threaded solution. Today because of the opportunity, I talk about my solution.This problem obviously has to consider two questions:1, multi-threaded issues2, algorithm performance problemsSome people think what algorithm performanc

Sieve of Eratosthenes (prime number screening algorithm) Given a number n, print all primes smaller than or equal to N. It is also given, N is a small number.For example, if N is ten, the output should be "2, 3, 5, 7″. If N is a, the output should be "2, 3, 5, 7, 11, 13, 17, 19″.The Sieve of Eratosthenes is one of the most efficient ways to find all primes smaller than n when n is smaller than mi Llion or so (Ref Wiki).Following is the algorithm t
