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.
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
14
代码如下:
#include <iostream> #include<stdio.h> #include<string.h> #include<algorithm> #include<stack> #include<queue> #include<deque> using namespace std; typedef long long ll; #define MAX 0x3f3f3f3f #define N 1005 struct bag { int c; int val; }bag; int main() { int t; struct bag a[1111]; cin>>t; while(t--) { int n,v; cin>>n>>v; for(int i=1;i<=n;i++) scanf("%d",&a[i].val); for(int i=1;i<=n;i++) scanf("%d",&a[i].c); int f[1111][1111]={0}; for(int i=1;i<=n;i++) for(int j=0;j<=v;j++) if(j-a[i].c>=0&&f[i-1][j]<f[i-1][j-a[i].c]+a[i].val) f[i][j]=f[i-1][j-a[i].c]+a[i].val; else f[i][j]=f[i-1][j]; printf("%d\n",f[n][v]); } return 0; }
附某大神代码:
- #include<stdio.h>
- #include<iostream>
- #include<queue>
- #include<cstring>
- #include<cmath>
- using namespace std;
- #define MAXN 1005
- int N,V;
- int vol[MAXN],val[MAXN];
- int dp[MAXN];
- int main()
- {
- int T;
- scanf("%d",&T);
- while(T--)
- {
- memset(dp,0,sizeof(dp));
- scanf("%d %d",&N,&V);
- for(int i=0 ; i<N ; i++)
- {
- scanf("%d",&val[i]);
- }
- for(int i=0 ; i<N ; i++)
- {
- scanf("%d",&vol[i]);
- }
- for(int i=0 ; i<N ; i++)
- {
- for(int j=V ; j>=vol[i] ; j--)
- {
- dp[j] = max(dp[j],dp[j-vol[i]]+val[i]);
- }
- }
- printf("%d\n",dp[V]);
- }
- return 0;
- }
