As you didn't show up to the yearly general meeting of
the Nordic Club of Pin Collectors, you were unanimously
elected to organize this years excursion to Pin City. You
are free to choose from a number of weekends this autumn,
and have to find a suitable hotel to stay at, preferably as
cheap as possible.
You have some constraints: The total cost of the trip
must be within budget, of course. All participants must stay
at the same hotel, to avoid last years catastrophe, where
some members got lost in the city, never being seen again.
Input
The first line of input consists of four integers: 1 ≤ N ≤ 200, the number of participants,
1 ≤ B ≤ 500000, the budget, 1 ≤ H ≤ 18, the number of hotels to consider, and
1 ≤ W ≤ 13, the number of weeks you can choose between. Then follow two lines for
each of the H hotels. The first gives 1 ≤ p ≤ 10000, the price for one person staying the
weekend at the hotel. The second contains W integers, 0 ≤ a ≤ 1000, giving the number
of available beds for each weekend at the hotel.
Output
Output the minimum cost of the stay for your group, or "stay home" if nothing can be
found within the budget.
