The visuals definitely help people get the gist of every principle. Then, coding becomes easy. Good article, Francesco Ciulla !

For more advanced use cases, the Java classes I have mostly worked with are in https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html . Nice and straightforward intro to regex, Sai Laasya Vabilisetty !

Thanks Richard Harris !

Many thanks Victoria Lo !

Happy to help Hrithwik Bharadwaj . Take your time to go through it. You'll be well prepared.

Thanks for the comment Tapas Adhikary ! Writing the article took a couple of weeks in total. I had already solved most of the problems over the past couple of years, but I had to come up with the right topics, review my notes, select the problems and the challenges, solve some new problems to better illustrate some of the techniques, and leave things out (probably the hardest part, because I really enjoy this).

Thanks Marvin Kweyu . I hope this helps the community.

That's a nice intro for your video!

Excellent intro! Thanks for sharing, Antonio Lo Fiego (He/Him) . I'd just add a link to a list of best practices when writing Dockerfiles that I have found useful at work.

I would advise, before you ask ANY question, ensure you have completed step 1 and 2. +1000. Great article, Bolaji Ayodeji . Thanks for sharing!
