[subhroacharjee]

Is your feature request related to a problem? Please describe.

we can make this repo better if we have a regex section where like we can document how to use regex, from basic (word detection) to advance (how to create a dfa from regex).
Describe the solution you'd like

I am not sure about the implementation so I need some more people to comment on this idea.
Describe alternatives you've considered

Well, this repo is focused on algorithms and I'm not sure if regex are somehow related to algorithms. It's a powerful tool for sure, but we're focused on different things here. I'm sure there are plenty of great resources about regex on the internet. Thanks for suggesting anyway!
