@[_LePetitPrince_](/user/255169) 没来得及看，你先对照检查一下：

update写错了，应该和query一样，包含在被修改的区间里才能修改
by Zzzcr @ 2023-08-04 16:23:11
@[Chtholly_is_so_cute](/user/564694) ok，我先看看
by __LePetitPrince__ @ 2023-08-04 16:24:10
@[Zzzcr](/user/761491) 可是我有不在区间里的忽略掉啊
```
if (r < pl || l > pr) {
return;
}
```

我感觉烦的应该是什么低级错误（但我就是没看出来（（
