Vreo idee cineva? Exceptand brute force  .

Toate variabilele sunt de tip long.. nu ma prind unde e greseala..

Cand pun solutia la problema pe site imi apare:

Eroare de compilare in evaluator: /usr/include/c++/4.2/bits/stl_iterator_base_types.h: In instantiation of 'std::iterator_traits<long int>': user.cpp:37: instantiated from here /usr/include/c++/4.2/bits/stl_iterator_base_types.h:129: error: 'long int' is not a class, struct, or union type /usr/include/c++/4.2/bits/stl_iterator_base_types.h:130: error: 'long int' is not a class, struct, or union type /usr/include/c++/4.2/bits/stl_iterator_base_types.h:131: error: 'long int' is not a class, struct, or union type /usr/include/c++/4.2/bits/stl_iterator_base_types.h:132: error: 'long int' is not a class, struct, or union type /usr/include/c++/4.2/bits/stl_iterator_base_types.h:133: error: 'long int' is not a class, struct, or union type

Am modificat doar conditia unui if fata de o sursa anterioara care mergea si local imi compileaza.

Este problema la evaluator sau la sursa?

Nu se mai pot ridica surse pentru a testa eventualele imbunatatiri aduse? 
Multumesc! Oranizare faina chiar daca de la 12 55  nu s-au mai putut uploada surse.
