Longest sub-array of Prime Numbers using Segmented Sieve

WebSieve of Eratosthenes is an algorithm that helps to find all the prime numbers less than a number N. The algorithm works by removing the numbers not meeting some mentioned criteria. Hence, the multiples of known prime numbers get eliminated, and the time to find all the prime numbers up to a limit is minimum.

The algorithm works iteratively by marking the multiples of each prime as non-primes (composite) because we are sure that if any number is a multiple of some other number, then it can never be prime. For example, if 2 is a prime number, then all ...
