Problem Description

Many years ago , in Teddy’s hometown there was a man who was called “Bone Collector”. This man like to collect varies of bones , such as dog’s , cow’s , also he went to the grave …
The bone collector had a big bag with a volume of V ,and along his trip of collecting there are a lot of bones , obviously , different bone has different value and different volume, now given the each bone’s value along his trip , can you calculate out the maximum of the total value the bone collector can get ?

 

 

Input

The first line contain a integer T , the number of cases.
Followed by T cases , each case three lines , the first line contain two integer N , V, (N <= 1000 , V <= 1000 )representing the number of bones and the volume of his bag. And the second line contain N integers representing the value of each bone. The third line contain N integers representing the volume of each bone.

 

 

Output

One integer per line representing the maximum of the total value (this number will be less than 2 ³¹).

 

 

Sample Input

1 5 10 1 2 3 4 5 5 4 3 2 1

 

 

Sample Output

code:

 1 #include<iostream>

 2 using namespace std;

 3 

 4 int main()

 5 {

 6     int N,V;

 7     int n[1001],v[1001],dp[1001];

 8     int T;

 9     int i,j;

10     while(~scanf("%d",&T))

11     {

12         while(T--)

13         {

14             scanf("%d%d",&N,&V);

15             for(i=1;i<=N;i++)

16                 scanf("%d",&v[i]);

17             for(i=1;i<=N;i++)

18                 scanf("%d",&n[i]);

19  //------------------------------------------------------------------------------------------------------------- 

20             memset(dp,0,sizeof(dp));

21             for(i=1;i<=N;i++)

22                 for(j=V;j>=n[i];j--)

23                 {

24                     if(dp[j-n[i]]+v[i]>dp[j])

25                         dp[j]=dp[j-n[i]]+v[i];

26                 }

27  //------------------------------------------------------------------------------------------------------------- 

28             printf("%d\n",dp[V]);

29         }

30     }

31     return 0;

32 }
