If we want to erase the element pointed to by ri, we can’t just use i, because i doesn’t point to the same element as ri. Instead, we must erase the element preceding i. Hence,

• To emulate erasure at a position specified by a reverse_iterator ri, erase at the position preceding ri.base() instead. For purposes of erasure, ri and ri.base() are not equivalent, and ri.base() is not the iterator corresponding to ri.

It’s worth looking at the code to perform such an erasure, because it holds a surprise.

vector<int> v;
