Prime number - a number can devide by itself or 1 so now we can iterate loop 2 to n/2 , if n is devide by any number from 2 to n/2 then it is not prime . loop : i = 2 <= n/2 if mod(n/i == 0)

8 paź 2024 · How to find the prime number list in Python? To find a list of prime numbers up to a given number, you can use the Sieve of Eratosthenes algorithm. def sieve_of_eratosthenes(limit): is_prime = [True] * (limit + 1) p = 2 while p * p <= limit: if is_prime[p]: for i in range(p * p, limit + 1, p): is_prime[i] = False p += 1
28 lut 2024 · A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. For example, given the input 29, the desired output would be True, indicating that it is a prime number. Method 1: Naive Approach. The naive approach checks if the number has any divisor between 2 and the number itself.
