    Task:
    https://web.facebook.com/photo.php?fbid=987931031542534&set=p.987931031542534&type=3&theater

    The task is vague and confusing.

    What is int& k and int &p in
    double findK(int& k, int &p) ?

    Why does a function get an argument k when it should return a value of k ?

    3 ^ 23 != 12167

    Arguments should be pointers to n and p.

    return 0;
