这个应该不是套取数据

@[nr0728](/user/682739) 改了一点细节，应该能更优
```cpp
#include <cstdint>
#include <cstring>
#include <iostream>
#include <sys/mman.h>
#include <sys/stat.h>
main()
{
struct stat st;
fstat(0,&st);
auto c=(char*)mmap(nullptr,st.st_size,1,2,0,0);
auto n=0u;
while
(*c>47)n=n*10+(*c++-48);++c;++c;
int s=0;
unsigned a[0x10000],v,p;
memset(a, -1, 0x40000);
for(int i=48;i<=57;i++)
for(int j=48;j<=57;j++)
a[(i<<8)+j]=(j-48)*10+(i-48);
for(;n--;c++)
{
v=p=0;
c+=p=*c==45;
while(~a[*(uint16_t*)(c)])v=v*100+a[*(uint16_t*)(c)],c+=2;
if(*c>='0')v=v*10+((*c++)^48);
s+=p?-v:v;
}
printf("%d",s);
}

说明肯定是有优化空间的（（
