输入 `4 2` RE，原因：`L.erase(it)` 之后 `it` 可能变成野迭代器

为什么要用list 不要用标记数组更简单吗

@[Donotplaygame](/user/549499) 感谢，已AC
附AC代码(※码风不良)
```cpp
#include<bits/stdc++.h>
using namespace std;
int n,m,now=1;
list<int> L;
int main()
{
cin>>n>>m;
for(int i=1;i<=n;++i)
{
L.push_back(i);
}
list<int>::iterator it=L.begin(),tmp;
while(!L.empty())
{
if(it==L.end())
{
it=L.begin();
continue;
}
if(now==m)
{
tmp=it;
it++;
cout<<*tmp<<" ";
if(it==L.end())
{
L.erase(tmp);
it=L.begin();
now=1;
continue;
}
else
{
L.erase(tmp);
now=1;
continue;
}
}
if(L.empty())
{
break;
}
now++;
it++;
}
return 0;
}
```

@[lao_wang](/user/701408) 想学一下stl里的list

可以用单向动态链表
