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.

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).

AC代码例如以下:
#include<iostream> #include<cstring> using namespace std; int main() { int t,n,v; int i,j; int a[1005],b[1005],dp[1005]; cin>>t; while(t--) { cin>>n>>v; for(i=1;i<=n;i++) cin>>a[i]; for(i=1;i<=n;i++) cin>>b[i]; memset(dp,0,sizeof dp); for(i=1;i<=n;i++) for(j=v;j>=b[i];j--) dp[j]=max(dp[j-b[i]]+a[i],dp[j]); cout<<dp[v]<<endl; } return 0; }
