这样真可以AC

@[sususu_123](/user/974547) 蒟蒻太蒻了导致理解不了 `long long int` 是什么意思

@[sususu_123](/user/974547) 真没见过这么开变量的
by heyx0201 @ 2023-11-08 21:37:02
@[heyx0201](/user/768951) 其实也没问题，一般跟longlong一样，不过因为比longlong多打个int所以用的人少而已

亲测，CPP100pts
贴代码
```cpp
#include<bits/stdc++.h>
#define MAX (9223372036854775807)
using namespace std;
typedef long long ll;
ll t,n,_time[100005],v[100005],f[10000005];
int main()
{
cin>>t>>n;
for(int i=1;i<=n;i++)
{
cin>>_time[i]>>v[i];
}
for(int i=1;i<=n;i++)
{
for(int j=_time[i];j<=t;j++)
{
f[j]=max(f[j],f[j-_time[i]]+v[i]);
}
}
cout<<f[t]<<"\n";
return 0;
}
```
应该差不多
