 (2) (since 哋它亢++23)

Returns the distance between basic_const_iterator and its sentinel.

S satisfies the exposition-only concept /*not-a-const-iterator*/ if and only if it's not a specialization of basic_const_iterator.

Parameters

i, s - iterator and sentinel to compute the difference of

Return value

1) base() - s
2) s - i.base()
