质数(prime number)又称素数,除了1和它本身外,不能整除以其他自然数,换句话说就是该数除了1和它本身以外不再有其他的因数:否则称为合数.最小的质数是2. 要判断一个整数N是不是质数很简单,看它是否能被2到sqrt(N)之间的整数整除即可. def isPrime(n): if n%2==0: return False for i in xrange(3,int(math.sqrt(n)+1),2): if n%i==0: return False return True 不过要找出1…

My first idea was Sieve of Eratosthenes, too. But obviously my coding was not optimal and it exceeded 6s time limit. Then I googled it. Sounds like Miller-Rabin Testing is a much more serious solution. http://www.cnblogs.com/feature/articles/1824667.…
