but in this case I need one regex and nothing more.
I always question design goals such as these. I distrust question posers who give such artificial requirements. It's a bit like watching an episode of MacGuyver, in how the responses come out.

Trouble is, programming isn't MacGuyver. We do have the ability to include a call to length somewhere, so why the artificial requirement?

Two reasons come to mind:

  1. The design that forced this decision is bad, in which case we must know more about the context to help redesign that part of the program, or
  2. It's Homework, in which case we should not answer the question at all.

I smell homework. Please prove otherwise, by stating the bad design decision more fully.
