刚才的代码偏移量加错了……（可是现在还是不过
```
#include <iostream>
#include <cstring>
#include <cstdio>
#include <algorithm>
#include <map>
using namespace std;
const int N = 410, delta = 1010;
int n;
int w[N], v[N];
int f[N + 10100];
int main()
{
cin >> n;
for (int i = 1; i <= n; i ++ ) cin >> w[i] >> v[i], v[i] = -v[i];
for (int i = 1; i <= n; i ++ )
for (int j = delta; j >= v[i] + delta; j -- )
f[j] = max(f[j], f[j - v[i]] + w[i] - v[i]);
cout << f[delta] << endl;
return 0;
}
```
