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 231).
Sample Input
1
5 10
1 2 3 4 5
5 4 3 2 1
Sample Output

题目大意：有一个骨头收藏家，他有一个容量为V的容器来收藏骨头。现在有N个骨头
各个骨头的价值为v[i]，各个骨头所占容量为w[i]。问他在容量为V的容器里，最多能
收藏总价值为多少的骨头？

scanf("%d",&v[i]);
for(int i = 1; i <= N; i++)
scanf("%d",&w[i]);
memset(dp,0,sizeof(dp));

for(int j = V; j >= w[i]; j--)

dp[j] = max(dp[j],dp[j-w[i]] + v[i]);
}
}
printf("%d\n",dp[V]);
