У вас две разные задачи под совершенно одинаковым названием: 1036, 1044 ("Lucky tickets")!!!!!!!! Я, например, ошибся.

Of course, you have to be attentive with that, because "Lucky tickets" is very popular problem :^) Use problem numbers, not titles - imho it's more convenient method.

And don't post Russian messages in webboard - respect others.
