In this program, we have checked ifnumis prime or not. Numbers less than or equal to 1 are not prime numbers. Hence, we only proceed if thenumis greater than 1. We check ifnumis exactly divisible by any number from2tonum - 1. If wefind a factorin that range, the number is not p...
The Sieve of Eratosthenes is an efficient algorithm to find all primes up to a given limit. It works by iteratively marking the multiples of each prime starting from 2. Example: Here is a Python program to print prime numbers from 1 to n. def sieve_of_eratosthenes(n): primes = [True]...
