RT，现在已经不能用如下的代码了：

#pragma GCC optimize(2)
#pragma GCC optimize(3)
#pragma GCC optimize("Ofast")
#pragma GCC optimize("inline")

所以这篇题解交上去会 CE，返回如下：

/tmp/compiler_9wtfro9q/src:2:9: 错误：‘#pragma GCC optimize’ is not allowed in online judge mode
    2 | #pragma GCC optimize(2)
      |         ^~~
/tmp/compiler_9wtfro9q/src:3:9: 错误：‘#pragma GCC optimize’ is not allowed in online judge mode
    3 | #pragma GCC optimize(3)
      |         ^~~
/tmp/compiler_9wtfro9q/src:4:9: 错误：‘#pragma GCC optimize’ is not allowed in online judge mode
    4 | #pragma GCC optimize("Ofast")
      |         ^~~
/tmp/compiler_9wtfro9q/src:5:9: 错误：‘#pragma GCC optimize’ is not allowed in online judge mode
    5 | #pragma GCC optimize("inline")
      |         ^~~
