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

代码：

#include <iostream>
#include <cstring>
#include <cstdio>
#include <algorithm>
using namespace std;
int t,n,m;
int map[1010][1010];
int dp[1010];
int max(int x,int y)
{
return x > y ? x : y;
}
int main()
{
scanf("%d",&t);
while(t --)
{
scanf("%d%d",&n,&m);
for(int i = 1;i <= n;i ++)
scanf("%d",&map[i][0]);
for(int i = 1;i <= n;i ++)
scanf("%d",&map[i][1]);
memset(dp,0,sizeof(dp));
for(int i = 1;i <= n;i ++)
for(int j = m;j >= map[i][1];j --)
dp[j] = max(dp[j],dp[j - map[i][1]] + map[i][0]);
printf("%d ",dp[m]);
}
}
