B. Bone Collector
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.
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
15 101 2 3 4 55 4 3 2 1
Sample Output
14
这道题和前面那一道苹果是差不多的。
代码:
#include<stdio.h>#include<string.h>#include<math.h>#include<algorithm>using namespace std;int f[1005]= {0},c[1005],w[1005];int main(){ int t; scanf("%d",&t); while(t--) { int n,v; scanf("%d%d",&n,&v); for(int i=0; i<n; i++) scanf("%d",&w[i]); for(int i=0; i<n; i++) scanf("%d",&c[i]); memset(f,0,sizeof(f)); for(int i=0; i<n; i++) { for(int j=v; j>=0; j--) { if(j>=c[i]) f[j]=max(f[j],f[j-c[i]]+w[i]); } } printf("%d\n",f[v]); } return 0;}
