reverse custom iterator

Question

Hi

Refer code below:
https://code.sololearn.com/c52WvnTAR09H

I just need same default behavior for reverse iterator as well. I mean for loop on rbegin and rend should also work with ++itr instead of currently working as --itr.

How can I do achieve the same?

You can use the std::reverse_iterator adaptor
