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.

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

题意：一个叫做Bone Collector的男的有一个包，往包里放东西，使得其价值最大。

输入：注意是先输入的是价值，后是体积。

分析：01背包裸题，注意格式输入输出就行了，我就是输入格式写错了，找错误找了一个小时，QAQ

下面给出AC代码：

 1 #include <bits/stdc++.h>
 2 using namespace std;
 3 int main()
 4 {
 5     int n;
 6     int v[1010],dp[1010],d[1010];//v代表体积，d代表谷歌值
 7     while(scanf("%d",&n)!=EOF)
 8     {
 9         while(n--)
10         {
11            memset(v,0,sizeof(v));
12            memset(dp,0,sizeof(dp));
13            memset(d,0,sizeof(d));
14            int x,y;
15            cin>>x>>y;
16            for(int i=1;i<=x;i++)
17               cin>>d[i];
18            for(int i=1;i<=x;i++)
19               cin>>v[i];
20            for(int i=1;i<=x;i++)//01背包主函数
21            {
22                for(int j=y;j>=v[i];j--)
23                {
24                 dp[j]=max(dp[j],dp[j-v[i]]+d[i]);
25                }
26            }
27            printf("%dn",dp[y]);
28         }
29     }
30     return 0;
31 }
