Implement the sieve of Eratosthenes: a method for computing prime numbers, known to the ancient Greeks. This method will compute all prime numbers up to n. Hints: Ask the user to provide an integer n. First insert all numbers from 2 to n into a set. Then erase all multiples of 2 (except 2); that is, 4, 6, 8, 10, 12, . . . Then erase all multiples of 3; that is, 6, 9, 12, 15, .... Go up to square_root of n (Erase all the multiples of square_root(n)) Then print the set.
