Is there a standard cyclic iterator in C++

Question

Based on the following question: Check if one string is a rotation of other string

I was thinking of making a cyclic iterator type that takes a range, and would be a

Answer 1

On the other hand, the very idea of cyclic iterator is not compatible to STL container ideology. You should not want cyclic iterator, as the user of this iterator may be surprized by its unusual behavior. Usually in STL you are iterating from the beginning to the end of container. Infinite loop in that case. Because the end is not reachable.

After all, obviously, you are not going to do more than 2 cycles to solve your task. No reason to have special iterator with confusing behavior. That is better to iterate usual linear container twice or may be even less then twice.
