如果评测机没炸就是你自己写错了。

@[pencil](/user/137723) 要是洛谷对快读有偏颇~~那就是成精了~~

可是真的WA了QWQ，可是如果我的快读有问题那么那六十五分怎么解释呢。。。

@[pencil](/user/137723) 把你的快读代码发一下？

@[wangzl](/user/222039)
```
typedef int ll;
ll read(){
char a=getchar();
ll f=1,o=0;
if(a=='-'){
f=-1;
a=getchar();
}
while(a>='0'&&a<='9'){
o*=10;
o+=a-'0';
a=getchar();
}
return o*f;
//int a;
//cin>>a;
//return a;
}
```

把
```cpp
if(a=='-'){
f=-1;
a=getchar();
}
```
更改为：
```cpp
while(a<'0'||a>'9'){
if(a=='-'){
f=-1;
}
a=getchar();
}
```
试试呢？

您这是快读还是慢读（hh

@[wangzl](/user/222039) 竟然过了QWQ，~~看来是输入了某些毒瘤的符号QWQ~~
