WebSieve of Eratosthenes. Your first task is to click on number 1. One is not a prime number as it does not have two factors. There is no simple formula for generating the sequence of prime numbers but this is a method devised many years ago by the mathematician Eratosthenes of Cyrene (he also invented Geography!). WebEven though the linear sieve has a time complexity of O(n), still, the time taken to iterate through the vector of primes, makes it slower when compared to the classic sieve of eratosthenes. In practice, the classic one with a few modifications like crossing out multiples of 2 in a separate loop and then only dealing with the odd numbers in the "main" …
