Expert Solution

I am hoping that you are aware about regular expressions, hence not discussing the basics of it. Directly I am jumping to answer your question.

A regular expression that can represent any digit:

[0-9]?\d+

A regular expression that can represent non digit characters. That means it will find only characters not the digits/numbers including spaces.

\D

Didnt got what are you asking with this statement. A regular expression that can represent without more than one digit. Please explain this so that I can answer.

If you are asking like to have single occurence of a digit then below expression can help.
