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
