@[protractor](/user/964822) 加了个st数组标记后不会在开O2的情况下不会RE了（
```cpp

@[protractor](/user/964822) 这下更灵异了，我把调试语句删掉以后RE了，然后加上就运行成功了。

谢谢大佬 @[QWQ_123](/user/740328)
这个代码没救了T_T，我重构吧
by protractor @ 2024-02-20 22:03:26
我dij写的和shi一样，就没有写对过一次
by protractor @ 2024-02-20 22:04:01
@[QWQ_123](/user/740328) 等等，RE了？？？？
by protractor @ 2024-02-20 22:07:52
~~第一篇代码创造的神贴~~
by protractor @ 2024-02-20 22:08:40
调试代码怎么你了 ~~@~~ IDE
by protractor @ 2024-02-20 22:09:49
@[QWQ_123](/user/740328) 本蒟蒻有几次不先加 `cout<<"";` 就没有输出

谢谢大家的帮助，问题解决了，是没有判断数组越界导致的RE
