Parenthesis ( ) around a regular expression can group that part of regex together. This allows us to apply different quantifiers to that group.

These parenthesis also create a numbered capturing. It stores the part of string matched by the part of regex inside parentheses.

These numbered capturing can be used for backreferences. ( We shall learn about it later )

(?: ) can be used to create a non-capturing group. It is useful if we do not need the group to capture its match.

Task

You have a test String .
Your task is to write a regex which will match with the following condition:

• should have or more consecutive repetitions of ok.

Note

This is a regex only challenge. You are not required to write a code.
You have to fill the regex pattern in the blank (_________).
