WebJul 5, 2024 · Efficient Approach: Sieve of Eratosthenes. The sieve of Eratosthenes is one of the most efficient ways to find all primes smaller than n when n is smaller than 10 million or so. Following is the algorithm to find all the prime numbers less than or equal to a given integer n by the Eratosthenes method: . When the algorithm terminates, all the numbers in … WebJun 15, 2024 · C++ Program for Sieve of Eratosthenes. Given a number n, print all primes smaller than or equal to n. It is also given that n is a small number. For example, if n is 10, the output should be “2, 3, 5, 7”. If n is 20, the output should be “2, 3, 5, 7, 11, 13, 17, 19”. …
