simple regex search+replacement

Question

All of the tutorials related to regular expressions I have found very difficult to understand, so thank you in advanced for helping me here on this stupidly simple question.

I'm trying to change a string of the form 0n to the form n so "02" => "2" and "06" => "6"

I know the search regex must be 0[0-9], but I don't know what the replacement regex must be.

Answer 1

Search Regex:

*(0)[0-9]+*

Replace $1, which would be group 1, a.k.a the 0 with ""
