~~求关~~
```cpp

注意用getchar_unlocked就刑
```cpp
#include<bits/stdc++.h>
#define int long long
namespace IO {
#define int long long
#define gh getchar_unlocked
inline int read(){char ch=gh();int x=0;bool t=0;while(ch<'0'||ch>'9') t|=ch=='-',ch=gh();while(ch>='0'&&ch<='9') x=x*10+(ch^48),ch=gh();return t?-x:x;}
inline char getc(){char ch=gh();while(ch<'a'||ch>'z') ch=gh();return ch;}
inline void write(int x){if(x < 0){putchar('-');x = -x;}if(x > 9){write(x / 10);}putchar((x % 10 + '0'));}
}
using namespace IO;
using namespace std;
signed main(){
register int n,a,ans=0;
n=read();
while(n--)a=read(),ans+=a;
write(ans);
}
```

@[Yxy7952](/user/936717) 请问我哪里错了

@[wang6w6](/user/1051310) 不用快写，不用 long long，快读函数加 inline 即可通过
