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 ?

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
1 5 10 1 2 3 4 5 5 4 3 2 1
Sample Output
14题目意思:有T组,每组有三行,第一行有两个数n(骨头数)和包的总体积,第二行是每个骨头价值,第三行是每个骨头的占用体积。输出要求背包能装最大的价值。#include<stdio.h> #define N 1010 struct nn { int w,usev; }bone[N]; int dp[N],V; int max(int a,int b){return a>b?a:b;} void zeroonepack(int use,int w) { for(int v=V;v>=use;v--) dp[v]=max(dp[v],dp[v-use]+w); } int main() { int t,n; scanf("%d",&t); while(t--) { scanf("%d%d",&n,&V); for(int i=1;i<=n;i++) scanf("%d",&bone[i].w); for(int i=1;i<=n;i++) scanf("%d",&bone[i].usev); for(int i=0;i<=V;i++) dp[i]=0; for(int i=1;i<=n;i++) zeroonepack(bone[i].usev,bone[i].w); printf("%d\n",dp[V]); } }
