Peter wants to generate some prime numbers for his cryptosystem. Help him! Your task is to generate all prime numbers between two given numbers! Input The input begins with the number t of test cases in a single line (t<=10). In each of the next t li…
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.…
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…
