iterator.h里面重载运算符是不是有问题呀

template <class Iterator>
bool operator>(const reverse_iterator<Iterator>& lhs,
               const reverse_iterator<Iterator>& rhs)
{
  return rhs < lhs; // 这个难道不应该是 !(rhs < lhs); 吗
}

不是呀，如果是!(rhs < lhs)，那如果他们相等不就返回true了，可以参考标准文档：https://eel.is/c++draft/reverse.iter.cmp ，我的实现不完全跟他一致，效果应该是一样
