`cin`耗费的时间会导致$TLE$

@[manyc](/user/826520) 使用``ios::sync_with_stdio(false)``关闭同步提速

@[manyc](/user/826520) 建议把 endl 换成 '\n',减少刷新输出缓冲区。

卡点常但不换 IO 方式能过前十个点而得 80 分。

加个简易的 `std::to_chars` 快输就过了。

加上```ios::sync_with_stdio(false)```
```cin.tie(0);```与```cout.tie(0)```;最后把```endl```改为```"\n"```就过了[评测记录](https://www.luogu.com.cn/record/107997037)
