10832 - Pouring Water   

Description

Suppose that you have an infinite number of containers with different sizes, already filled with water. Given another empty container with size N liters, you need to find out all the possible methods to fill this N-liter empty container using the provided smaller containers. Note that, to avoid water wastage, if you choose to use a container, all the water in this container should be poured.

For example, assume that we have containers in 1, 5, and 10 liters. To get the 17 liters of water, all the possible methods are listed below:

  1. 1 container of 10 liters, 1 container of 5 liters, and 2 containers of 1 liter.
  2. 1 container of 10 liters, 0 containers of 5 liters, and 7 containers of 1 liter.
  3. 0 containers of 10 liters, 3 containers of 5 liters, and 2 containers of 1 liter.
  4. 0 containers of 10 liters, 2 containers of 5 liters, and 7 containers of 1 liter.
  5. 0 containers of 10 liters, 1 container of 5 liters, and 12 containers of 1 liter.
  6. 0 containers of 10 liters, 0 containers of 5 liters, and 17 containers of 1 liter.

Note that

1.      This problem involves three files.

  • function.h: Function definition of filliing and showResult.
  • function.c: Function describe of filling and showResult.
  • main.c: A driver program to test your implementation.

You will be provided with main.c and function.h, and asked to implement function.cpp.

2.     For OJ submission:

       Step 1. Submit only your function.c into the submission block. (Please choose C compiler) 

       Step 2. Check the results and debug your program if necessary.

function.h

main.c

 Hint 

You can use the following incomplete code of function.c to solve this problem.

function.c

Input

The input contains three lines.

The first line contains an integer M (0<M<=5) which represents the number of different size containers.

The second line contains M numbers, S1 ,S2 , …, SM. Si represents the size of the i-th container. Note that these M numbers are in decreasing order.

The third line contains an integer N (0<M<100) which represents the size of the empty container.

Output

Display all the possible methods to fill the empty container. Each line represents a method in the format “(C1,C2,…,CM)”, where Ci represents the number of the size Si container.
