添加头文件 `#include<algorithm>`

@[PuJunXi](/user/1011579) 你用了 `std::max` 但是没有头文件

看的 CE 信息就能看出来（来自洛谷在线 IDE），是不会看吗
```plain
/tmp/compiler_pnc657rm/src: 在函数‘void bag()’中:
/tmp/compiler_pnc657rm/src:10:65: 错误：‘max’ is not a member of ‘std’; did you mean ‘fmax’?
10 | if(p[i]==0) for(int j=t[i];j<=ti;j++) f[j]=std::max(f[j],f[j-t[i]]+c[i]);

| fmax

它不爆CE信息啊 @[H3PO4](/user/178437)

估计是本地的cmath自带std::max，g++版本不一样

@[PuJunXi](/user/1011579) [这（你的提交记录）](https://www.luogu.com.cn/record/129007069)不有吗

我用的小熊猫2.24

显示不出来

但是你交到这里 CE 了你也应该看一下它显示的信息吧
