int main ()
    {
    std::string input;
    std::cin>>input;
    Std::string::iterator First=input.begin (), Last=input.begin ();
    while (Last!=input.end ())
        {
        int cnt=0;
        while (Last!=input.end () && *first==*last)
            {
            ++cnt;
            ++last;
        }
        std::cout<<cnt<<*first;
        i = Last;
    }

    return 0;
