WebJan 15, 2024 · Below are steps used in Segmented Sieve. Use Simple Sieve to find all primes up to the square root of ‘n’ and store these primes in an array “prime []”. Store the found primes in an array ‘prime []’. We need all primes in the range [0..n-1]. We divide this range into different segments such that the size of every segment is at-most ... WebC N is nonempty. By well-ordering, C contains a smallest element m. Note that m can’t be prime itself. So there is some integer d such that d divides m and 1 < d < m. But now, e Dm=d is also an integer such that e divides m and 1 < e < m. By the minimality of m in C, we know d and e are both products of primes.
