这个帖子编译不能通过，说是定义set时出错，不知道是什么原因
C:\Program Files\Microsoft Visual Studio\MyProjects\s13\s13.cpp(30) : error C2664: '__thiscall std::set<int,struct std::less<int>,class std::allocator<int> >::std::set<int,struct std::less<int>,class std::allocator<int> >(const struct std::less<int>
&,const class std::allocator<int> &)' : cannot convert parameter 1 from 'class std::list<int,class std::allocator<int> >::iterator' to 'const struct std::less<int> &'
Reason: cannot convert from 'class std::list<int,class std::allocator<int> >::iterator' to 'const struct std::less<int>'
No constructor could take the source type, or constructor overload resolution was ambiguous
