I have watched some of the lectures those were very understandable thank you ma'am

(a+ϵ).(b+ba)*. Mam How to write this regular expression to simple English.

[manjoydas]

Ans for qus 3 is perhaps wrong here. It should be (a+ab)^+ since the regex in the video is also accepting epsilon which is not desired. Education 4u must post the correct answers in comment box if there is any mistake in the video.

[shivendratripathi]

In question 3 it should be + instead of a * as we have start a string from a and empty string is not accepted na?

[newspresentersacdemybd]

If the R:E: for number 3 is= (a+ba)* then whether it would be wright or wrong?? Plz let me know as soon as you can.
