The simple sieve of eratosthenes is an algorithm that is used to find prime numbers in the range 1 to a given n. In the sieve of Eratosthenes algorithm, we maintain a boolean vector of numbers from 1 - n, and mark composite numbers as False. This is done by taking the smallest numbers starting from 2, and then marking it's multiples ...
