Event Planning |
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.
The first line of input consists of four integers:
1 N 200
For each test case, write to the output the minimum cost of the stay for your group, or ``stay home''
if nothing can be found within the budget, on a line by itself.
