long long primes[] ={ 2, 3, 5, 7, 11, 13, 17, 23}; // TODO: ADD THE REST OF THE PRIMES HERE
long long num = 8; // number of primes goes here
int main()
{
     int input = 0;
     printf("number:");
     scanf("%d",&input);
     for(int i = 0; i < num; i++)
     {
          if(primes[i] < input)
          {
               printf("%d",primes[i]);
          }
     }
     return 0;
}
