也许你的数组开小了。。。

@[lucy2012](/user/1252442) 数组这么开就行了：
```cpp
dp[25][30000],w[25],v[25]
```

```
#include<bits/stdc++.h>
using namespace std;
int w[30],v[30],dp[500000];
int n,m;
int main(){
cin>>m>>n;
for(int i=1;i<=n;i++){
cin>>v[i]>>w[i];
w[i]*=v[i];
}
for(int i=1;i<=n;i++){
for(int j=m;j>=v[i];j--){
if(j>=v[i]){
dp[j]=max(dp[j],dp[j-v[i]]+w[i]);
}
}
}
cout<<dp[m];
return 0;
}
```
