双向队列rend函数运用实例

rend
语法:

1	reverse_iterator rend();

rend()返回一个指向双向队列头部的逆向迭代器。

源代码/**

* Returns a read/write reverse iterator that points to one before the

* first element in the %deque. Iteration is done in reverse element

* order.

reverse_iterator

rend() { return reverse_iterator(this->_M_impl._M_start); }

/**

* Returns a read-only (constant) reverse iterator that points to one

* before the first element in the %deque. Iteration is done in reverse

* element order.

const_reverse_iterator

rend() const

{ return const_reverse_iterator(this->_M_impl._M_start); }
