Answer 1

Muhammad Abdullah ,

maybe some samples input and output could help us. also a brief description would be a good idea.

if it is just the regex part that causes an issue for you, just give a description of what inputs could be and what you expect to get by using regex.

Also, instead of pasting a wall of code in the question description, add a link to your code in Code Playground (use "+" button). This allows people to test and debug your code.
