@[whiterrr](/user/215166) 这种情况不应该把你的 read() 发出来么。。。

那就是快读出锅的呗

@[whiterrr](/user/215166) 你快读类型是long long吗

```
// 读入优化
inline ll read() {
ll f, x;
f = 1, x = 0;
char ch = getchar();
while(ch < '0' && ch > '9') {
if(ch == '-')
f = -1;
ch = getchar();
}
while(ch >= '0' && ch <= '9') {
x = x * 10 + ch - '0';
ch = getchar();
}
return x * f;
}
```

@[Dzhao](/user/108610) 是的
by whiterrr @ 2020-02-06 13:41:11
@[whiterrr](/user/215166) `ch < '0' && ch > '9'`改为`ch < '0' || ch > '9'`

@[whiterrr](/user/215166) 第一个 ``while`` 里应该是 ``||``不是``&&``
