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 , eac
4000
h 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

题目大意:骨头收集者去古墓收集骨头,带一个容量为V的背包,求在背包容量允许的情况下,求价值最大,每一个骨头对应一个价值
解析:简单的 0-1 背包,直接循环一下就好了
代码如下:
#include<iostream>
#include<algorithm>
#include<map>
#include<stack>
#include<queue>
#include<vector>
#include<set>
#include<string>
#include<cstdio>
#include<cstring>
#include<cctype>
#include<cmath>
#define N 1009
using namespace std;
const int inf = 1e9;
const int mod = 1<<30;
const double eps = 1e-8;
const double pi = acos(-1.0);
typedef long long LL;
int dp
, a
, b
;
int main()
{
int v, n, t, i, j;
cin >> t;
while(t--)
{
scanf("%d%d", &n, &v);
for(i = 1; i <= n; i++) scanf("%d", &a[i]);
for(i = 1; i <= n; i++) scanf("%d", &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], dp[j - b[i]] + a[i]);
}
}
printf("%d\n", dp[v]);
}
return 0;
}
