friend constexpr /*iterator*/ operator+( const /*iterator*/& i, difference_type n )     requires ranges::random_access_range<Base>;	(1)	(C++23 起)

令 parent_ 与 inner_ 为迭代器的数据成员。

1,2) 等价于 return /*iterator*/(*i.parent_, i.inner_ + n);。

3) 等价于 return /*iterator*/(*i.parent_, i.inner_ - n);。

4) 等价于 return i.inner_ - j.inner_;。

这些函数对常规的无限定或有限定查找不可见，而只能在 adjacent_transform_view::iterator<Const> 为实参的关联类时由实参依赖查找找到。

参数

i, j	-	迭代器
n	-	相对于当前位置的偏移量

返回值

1,2) 增加后的迭代器。

3) 减少后的迭代器。

4) 给定迭代器之间的距离。
