void update(int* a, int* b);

int main() {
    /* Enter your code here. Read input from STDIN. Print output to STDOUT */   
    int a,b;
    std::cin >> a >> b;
    update(&a, &b);
    std::cout << a << std::endl;
    std::cout << b << std::endl;
    return 0;
}

void update(int* a, int* b)
{
    int tempA = *a;
    int tempB = *b;
    
    *a = tempA+tempB;
    *b = abs(tempA - tempB);
