I have 10 years IT experience and so far I never bother learning about regex, yet the irony is i almost use it on day to day basis. I simply Google and copy-paste the regex. Your video helped me understand the basic concept very well!

In the second task You have a little bug. The task "only one digit allowed in between" indicates that the last [a-z] should have not * (0 or more) but + (1ore more). Otherwise the digit will not be between the letters. Everything else is just beautifull and simply shown

* is for the number of repetitions not for the number of characters for instance [a-z] * simply means it should atleast have 1 character between a to z and * there means 0 and more repetitions are possible do correct me if I'm wrong

I am new to programming. Thank you for your work. 1. I'd like to know, on your answer for question 2 you used * instead of + which according to me is what will make sure that there is atleast one lowercase 2. on the last question you chose to use {2,3}, if I understood your explanations well that quantifier will allow only 2 chars since 3 in not included. {y,z} means atleast y times but less than z times. So according to my small understanding {2,4} would be more accurate in this case. please do correct me if I am wrong. by the way this content is the best
