int main() {
    // Update your code below this line
    int n,i,temp=1;
    scanf("%d",n);
    
        for (int i=2;i<=sqrt(n);i++){
            if(n % i==0){
                temp=0;
                break;
            }
        }
        if (n<=1)
        temp=0;
        if(temp==1)
        {
            printf("Yes\n");
