Dear experts,

I'm writing my assignemts and I don't know if I'm on the right track.

Could you give me some advices? Thank you.

2.Describe the following regular expression in natural language. Include two examples of strings that match and two examples of strings that do not match. [5 points] /[abcd](\)|\.)([0-9]{3,}\s*[\^wb\-])/g

The expression is under global flag (/.../g), which means it will finds all matches. In other words, it will locate all potential matches instead of terminating after the first match. [1]

Then, the expression can be seperated into parts as listed below for easier understanding :

[abcd] identifies one of the characters 'a', 'b', 'c', or 'd'.

(\)|\.) means either a ')' or a '.' character.

([0-9]{3,}\s*[\^wb\-])/ means 3 or more digits randomly picked from the range of 0 to 9, possibly separated by white space characters, and finally ending with either '^', 'w', 'b' or '-'.
